Using the rinnie as a major heating source for an older home

I have an older home with no central heat. My house is about 10 to 15 feet from a commoecial building. At times the wind blows very strongly between the two buildings. I was considering a direct vent heater(Rinnai) Would this be a good idea? If not what could be used?

The smaller the vent the better. A Rinnai may heat an area just fine but a whole house is pushing it.

Free heat from your own furnace

to greatly increase the efficiency of all forced air heating systems use aluminum duct tape and tape all joints in the ductwork The hot air ducting from the furnace right to the register in the floor or walls should be air tight to keep heat from escaping .Also the cold air returns and all associated ducting should be taped at all joints to ensure maximum air flow . Taping all ducting will not only provide more heat to all rooms of your house it will also produce less dust from leaking cold air ducting which sucks in air and dust from areas typically not cleaned (wall and floor cavities) . I did this in my older home and found I had to close off some registers because of the huge increases of volume which provided extra heat volume for the rooms that needed it.The house is now consistantly warm in all parts

Solar Air Heating - You Can Cut Utility Costs and Save Money

Solar energy is becoming very quickly recognized as one of the best alternatives to fossil fuels It is an abundant and renewable natural resource. It can be used to save energy in residential, commercial, and industrial settings. Solar technologies will use the sun's energy to provide heat, hot water, light, electricity, and cooling, for homes, businesses, and industry.

Many major advancements have been made in the solar technology fields over the recent years. Solar air heating is becoming more attractive than ever before now that it is becoming lower in cost and more efficient. Solar energy is easily the cleanest and most inexhaustible of any of the known energy sources. The many variations in energy prices have fueled interest in alternative fuels such as solar energy. Demand for solar energy has been increasing exponentially as heating, cooling and many other energy costs continue to skyrocket.

Solar air heating and solar water heating are two examples of solar thermal technologies which produce heat, but not electricity. Solar air heat is best suited for installation in new construction and existing houses. Solar panels for any type of heating should be placed on a south-facing pitched roof, free of shade. The angle should be between 20 and 50 degrees. They may also be mounted on an angled frame on the ground or on a flat roof. Solar air collectors (the devices that heat up the air using solar energy) can directly heat individual rooms. They also can potentially pre-heat the air passing into a heat recovery ventilator or the air of an air-source heat pump. Solar heating panels can be one of the most cost effective ways to reduce your utility bills. This will make a positive contribution towards a better environment. Solar air heating systems often use large bins filled with rocks that store heat (although this method is becoming rare due to problems associated with controlling moisture and mold growth in the rock).

Energy Policy Act has implemented a 30% tax credit for consumers who chose to install solar water heating systems. State and local government programs are now being put in place to encourage the use of solar energy. Cash incentives are available for those that integrate solar energy technology as an alternative energy source. The Department of Energy (DOE) is working to design even more cost-effective solar heating systems and to improve the longevity of the materials used in those systems. Other incentive programs now include offering homeowners tax credits for solar panel installations and for solar heating systems. With solar power you will save money, increase your property value, help protect the environment and help to create a more secure America by reducing our dependence on foreign energy fuel sources.

A great solar heating system will save energy, reduce utility costs, and produce clean energy.

I am getting ready to buy baseboard heat for a 800-900 squarefoor open area, old GArage, And I am looking at 3 8' 2500W sections of base board. is this enough. And How much better is the units you have...

First, those of us on FixYa don't sell any products or appliances. Just information.

But to answer your question about electric baseboard heating ... It's the most inefficient and costly heating source you could use. With that said, a lot depends on the cubic footage of the area, as well as how well that area is insulated. This applies for electric, gas or oil heating. You rae not just heating square footage, you're wanting to heat cubic footage (i.e. Width x Length x Height = Cubic Footage). Assuming you have an 8 ft ceiling, the Cubic Footage would be (assuming a 9 ft ceiling) 7200 Cubic Feet. Based on that and if it was my home, I'd be installing a 20,000 - 25,000 Btu Vent-free (Flue-Less) Gas Heater, with built-in thermostat control. It could either be as a Free Standing, Vent-free Gas Fireplace System or simply a Wall Mounted Heater. One is decorative, as well as efficient and the other is simple and efficient. Plus, gas heat is a warm, moist heat that you feel very quickly and it's more comfortable than electric or oil heat. As a matter of fact, Vent-free Gas Heating Appliances are 99.9% efficient. And will work without electricity. Which is great during a Winter power outage. If you currently don't have Natural Gas at your home, then LPG (Liquid Propane Gas) is readily available.

So, by now, you figured out that my preference is gas. I have three Vent-free gas heating appliances in my 3000 square foot home (2-Vent-free Remote Controlled Gas Log Sets in existing wood burning fireplaces & a Vent-free heater in my 2-car garage). Our primary heat source is an electric heat pump. Which doesn't work well, when the temperature reach 32 degrees F or lower. We use the gas heaters only as a supplement heat source or as primary source, if the power goes out.

I hope you'll take a little time to research this, because in the long run, it can save you $$$. Below, is a link to Empire Comfort Systems. They have excellent supplemental and primary heating products in all looks, shapes and sizes. This will give you an idea of what's out there.

I hope all of this helped you. Please let me know. Thanks.

I am putting baseboard hot water heat in an older house that hase outlets in the way, is it alright to mount the baseboard above outlets . It would be about 12 inches.

Not sure that would pass code. But, you may want to check with the local building inspections dept in your area, before doing it. The other down side will be, the heat will start 12" of the floor rather than floor level. As you are aware, heat rises, so that would mean the lower 12" to the floor is going to remain cold. Want feel very good on bare feet that just jumped out of bed.

I just move in to this house, and I figure out that the gas consumption is to hight. The gas bill this month is close to $200.00. I want to know if that is the average cost to keep my small house warm....?

well depending which country you live in and what price your consumption is per kilowatt. And are you running the thermostat at low comfortable temperature instaed of high temperatur set points that just waste money also has the unit been sized right for area its heating if not it will run more longer than it needs in some cases the heater never turns off becuase it can't beat the cold as it is to small for area, look there could be a many a factors to why it coast this much but it also comes down to a well insulated house as well, when it comes to heating its just common sense to make sure your house will retain heat and hold out the cold firstly before making sure heater is good enough any heater is good enough as long as your house can hold the heat in and with central heating with gas it should only take about an hour to warm the house any longer and it maybe undersized so run heater for about half an hour if it doesn't seem to feel warmer around you it could be heater to small but if heater sized right and insulated right through and you run about 18 or 20 degrees centigrade (australin temp you'll have to convert fernhieght if u.s.), if you try trhis your coast should come down, alot of people also turn up temperature to get more heat well you don't get more heat it just runs longer than it needs too which will coast you more, whatever temperature you set it will always run the same temperature out of air supply, so another money saver is over night and while your out turn down about 6 or 7 degrees then turn back up when your up or home, i know people who run on L.P.G (propane bottle gas depending where you are again) and spent about $300 to $400 a month and if your on a gas reticulation ((natural gas)we call town gas here as its only where they have run pipes here to peoples house so five minutes out of city and its the more expensive bottled gas **** as i can't get town gas and its very cheap apparently), its cheaper again on natural gas! so there are many factors involved on central heating it pays when getting these systems to research and find a installer that knows what he's talking about than a cowboy i've replaced about 6 this year due to undersizing by other companies that obviously are only after money, just about to finish my last one on monday and already told client that they will be happy no ifs or butts i know they will be happy as i have sized correctly and re done most ducting under floor as whoever installed had no idea about air flow and how important it is on central heating! i would get an central heating engineer to look at it for you (someone form a place that didn't install it they like to lie and blame everything else except the obvious that they have ripped you off and deffinatly don't want to give anything back, but honestly $200 sounds slightly high but probably not really that much higher than norm. do you have friends with same sort of heater if you do ask them how much they pay a month and compare

I am looking for basic information regarding forced air space heaters. When the specs indicate "will heat xxxxx sq. Ft space, what does that actually mean? A "Space" is often measured in...

The basic method that i've used for years is using square feet of floor space. There are all sorts of multipliers in different calculations dependent on number of windows, type of insulation, numberof doors to exterior, area of the country you live in and number of people in your house.
We live in north central Kansas and it gets plenty cold and hot here. I figure 1 ton of cooling for each 500square feet of space and 40,000 B.T.U. s for heating. This is just a quick way to figure and around here it works pretty well.
I always thought it was better to err on the side of a little more is better then a liitle less.
Hope this helps you some. Thanks

I have hot water but the central heating has stopped working

Your heating system is separate from your domestic hot water. This means that you probably have an electric or gas appliance dedicated to heat water for your home.

Your problem will be found with your furnace or fuel supply. Since it is not unusual to heat water with a different fuel (electric, gas, etc.) than you do to heat your home, one can work while the other does not. Your first check should be to determine which energy source is required for your home to be heated. Home Heating Oil, Natural Gas and Propane are very common fuels. Additionally, many of these systems require some sort of electric supply to provide power for controls, pumps, sensors, etc.

Check for blown fuses and tripped circuit breakers in the electrical panel. Restore any failed circuit found. Check fuel level gauges. Arrange for refueling if you are out of fuel. If heating with Home Heating Oil, the delivery driver will probably need to manually prime and start your furnace before it will work automatically again.

You may also have a defective thermostat, control or sensor. Additionally, the furnace may have detected an unsafe condition when last run, and shut down as a safety precaution. If any of these things have happened, you'll probably need to have a pro check it out and make the required repairs for you. You could start by contacting your fuel company to see if they offer service. Otherwise, check telephone listings for someone that does.

Hopefully, this helps you atleast find someone who can get the heat back on for you - good luck!

Heating the house causes breathing issues

if your ducts come off the end of your supply plenum and not the middle this could cause a problem in that the air doesn't have time and a place to mix before it leaves the plenum to the ducts. should be at least 12" from ducts to the end of plenum. i find this problem alot.
