Gas Boiler Condensing Best Features

Condensing boilers are the most efficient way to heat that there is today. The BTU’s that they wring out of the fuel put into them is the best of anything available today. Not only do they burn their fuel very well, they also have technologies built into them to help give then the highest efficiency possible on any given day.

Condensing gas boilers have been on the market for about twenty years now. The early boilers were noisy and very heavy. Today’s condensing boilers are not even remotely the same as their predecessors. There have been many improvements that make these boilers lighter, safer, and more reliable than ever.

Many of today’s condensing gas boilers are controlled by a computerized control that gives many options and features to customize your boiler to the type of system that it is being installed in. Not only does the control monitor the boiler, but it can be setup to control the whole heating system as well. This gives the added benefit of fewer controls and the saving of space. Circulator pumps, mixing controls, and injection pumps can all be controlled by the boiler control.

These technologies are things like sensors to make sure that they are running at the highest combustion efficiency possible or they will shut down. Outdoor reset controls will vary the water temperatures to make sure that the water temperature is only being heated as hot as is needed to make your house warm at any given outdoor temperature.
Sensors also monitor the supply and return water temperatures constantly to shut down the boiler if the boiler senses any unsafe conditions.
These boilers are so good that even if you fire the boiler before filling it with water, the boiler will shut off before it is damaged.

When looking at the boilers on the market today take into consideration all of the benefits of that the newer high efficiency boiler have to offer. High efficiency is really great, but there is so much more to them. The ease of installation because of the light weight of new condensing technology, the versatility of the controls that are incorporated into these boilers, and the outdoor reset technology that will save you fuel and make you much more comfortable.

Boiler Energy Saving Controls They can save You Money

I was recently emailed a question by a fellow that wanted to know if an outdoor reset control would help him cut fuel oil costs for a seasonal home in that was only used occasionally in the winter. The short answer is yes, however there may be a better control for him and his particular circumstance.

Energy saving devices are great things in many ways and they usually do save you money. The problem is that you need to use the right device for the job that you want to do. Using the right control to do the job you need is the question that needs to be answered. Just because you spend a lot of money on a control it does not mean that you will save a lot of money.

What kind of fuel are you burning? What type of boiler do you have and at what water temperatures can it be run at? These are a few of the critical questions you must consider.

If you have a condensing gas boiler and have a heating system that will heat at fairly low water temperatures for most of the season then an outdoor reset control will be worth installing. If you have an oil boiler that needs to run at hotter water temperatures to prevent condensation then you may want to use a different control.

Oil boilers often run a hot fire and usually are not piped in such a way as to get the heat away from the boiler as fast as it is produced. Because of this the boiler will be cycling many times an hour. This cycling will decrease the efficiency of the boiler and cost you money.

By installing a Beckett HeatManger on your oil fire hot water boiler you will make the run times longer and increase your efficiency. The Beckett HeatManager will smooth out the cycling and get you the comfort and efficiency that you want for much less money than many of the outdoor reset controllers. In many cases you will save the price of the control in a month. The best part is that many average do it yourself persons can install this control themselves!

Using the right tool to do the job you want will save you fuel, time, and money. Make sure that you find the right product to install before you just start throwing money at a problem.

Ferroli boiler optimax he 38 c.Powers up ok,no hot water,no error code.Think its an ignition problem.Heating flame not showing?????

Is there an error code? If not the flow sensor for the hot water could be faulty. Also if you've had a power cut depending which model of Optimax HE you have, you sometimes have to tell the boiler it's a Combi, as they have a generic Pcb fitted which is also used on the system only boilers.

Can't help you directly, but Honeywell will have user instructions on their website.
It's something like holding the 'stat within a metre of the boiler when the batteries are inserted. Best to RTFI.

Condensing Gas Boilers - The Best Radiant Heat Boiler

The right condensing gas boiler coupled with the right heat transfer system to get the heat into your home the right way will give you the most efficient heating system possible with today’s technologies. There are a few things that need to be taken into consideration for this combination to work well and serve you well.

For this type of heating system to work you first need to have a radiant heat system that will supply enough BTU’s to your home at very low water temperatures. By low I mean under 100F. To get the output that you need at this low a temperature you of ten will need to design the radiant heat system with heat transfer plates. The heat transfer plates will make the transfer of the heat from the tubing that the water flows in to the floor as efficient as possible. Getting the floor warm enough to heat your house with low water temperatures should be the goal.

Now that you have a great heat transfer system you can set up your boiler to run at very low temperatures also. Most of today’s condensing boilers use out door reset technology to assist in keeping the water temperature just high enough to help the heat transfer plates produce just enough heat to keep you warm. On the coldest day of the year you want your water temperature to be no more than 100F and still be keeping your house to the temperature that you want it to be.

A great high efficiency heating system coupled with a good high quality condensing gas boiler will give the best in comfort, quiet heating at the lowest cost possible. Sure this type of system will have a bit higher upfront cost. And the contractor that you hire to install this type of heating system may require a higher rate to perform the work, But once you experience the comfort and efficiency of a top notch heating system like this you will soon forget the money and enjoy your nice warm comfortable home.

Unit will not lite

Look on the circuit board, is ther a flashing diagnostic code?

tell me this code sequence.
Typically an induced draft motor will be the first thing to run, is this running? is the pressure switch for the induced draft operating, it its tubing and the tubings ports clear?
is the condensate line clear?

is the flame sensor clean? use 0000 steel wool to wipe it off.

you can disconnect the white plastic condensate pipe from boiler and just let the condensate water from the boiler it drip into a bucket when the boiler is on untill the pipe defrosts then just reconnect it and make sure the condensate pipe is lagged outside
