Question about Williams 3003622 Ceramic Wall Mounted Panel Heater

1 Answer

I have a residential gas service from PG&E. What is my maximum heater size? PG&E said the maximum output is 250,000 btus. I have a 90,000 range and a 50,000 btu hot water heater. Does that mean my maximum heater is 110,000 btu?

I take it we are talking gas meters here , if so meters only pass so much gas, to there size so 250,000 is the max it will pass for that size meter if you need more you can have a bigger meter fitted , but this would cost you i would think ,so yes 110,000 is what you have left in btus on that size meter

I followed the instructions to a T. I turned my iHeater on using the--O switch located on the back. I adjusted the desired room temperature to 74 degrees. I adjusted the room size to Large. The iHeater...

I would read the customer reviews on this product , looks like nearly 70% of consumers are less than happy with this unit.

1500 watts is the units peak output, and drops to around 600 as it warms up. My hair blower puts out more power.

1500 watts is LESS than the output of a small element on your stove top. The real measure of heat is not watts, its BTUs and btus from gas are much cheaper than they are from electricity.

What size oil furnace is needed for 1200 square feet?

75000 to 85000 btu Or British thermal pound.
Two units of measure are important in sizing an oil furnace. The first is the British Thermal Unit or BTU, which represents the energy needed to raise the temperature of one pound of water by one degree Fahrenheit at normal atmospheric pressure. The input capacity of an oil furnace is often stated using this unit of measure. The second number is the fuel efficiency rating, which is expressed as a percentage. This represents the amount of energy that gets converted to heat, with higher numbers being better. To determine the energy output in BTUs per hour, multiply the input BTU by the efficiency rating. For example, a furnace with 100,000 BTU of input and an efficiency rating of 89 produces 89,000 BTUs of output. One with an efficiency rating of 80 and the same input amount, produces only 80,000 BTUs of output.

I am just trying to find out how many amps is needed for my pool heater. It says 73.2 kw and its 250,000 btus. Please advise

This sounds like a lot of power. If you divide 73200 by 230(V) then you should get about 318 Amps. This is an extremely high current. I hope this helps.

Please vote on this answer. Thank you.

I have a wall mount vent free heater and a 10 gal propane tank how do hook it up so it will work

First off, Dave, the tank cannot be inside the house, motor home, camper, garage, etc. By the way, I believe your 10 gallon tank, is what's called a 40LB cylinder. Anyway, 10 gallons is not going to last very long, if the heater you plan to install is 20,000 Btu output or higher. If it's going in a bedroom, the maximum Btu output can not exceed 10,000 Btu's.

To install one, you'll need 1/2" flexible copper gas piping. An in-line LP Gas regulator, that has the capacity to carry whatever the maximum Btu output of you heater is. In addition, you will need a 1/2 NPT to 3/8" Flare nipple to go into the back of the heater. Assorted Flare Nuts in assorted sizes for the gas line connections.

Tools needed: Flaring tool, 2 adjustable wrenches, Phillips Head Screw Driver & Leak Detector Solution. To make sure it's done correctly, a Mechanical/Plumbing Permit from you city or county's Building Inspection Department. And last, but not least, a friend that has a lot of knowledge in the installation of Vent-free Supplemental Gas Heating Appliances.

If installed properly, these appliances are very safe. If installed improperly, they can be very dangerous.

I am replacing my old 400,000 btu natural gas pool heater with a Hayward 250FDN, which will be adequate because I plan only to heat the spa, not the whole in-ground pool. My question is how much of the...

This should be an easy installation. PVC is easy to install as stated above. Electrical, just follow the directions in the installation manual. As far as the gas line goes, you CAN use a flex line in place of the black gas piping for the 2 feet BUT make sure it is adequate for the amouont of BTUs you will be running. ALL flex-gas pipe has a rating on the side of that will indicate the maximum amount of BTUs that can run through the pipe. The highest rated flex Ive seen @ 2 feet is for 297,000 BTUs. You should be fine at 250000. Chances are the local hardware store will not have this good flex pipe though. You will have to goto a local HVAC store to aquire it.

depending on the heat load calculation and the geographical location you live in a normal rating would be around 30000 btu per 1000 square feet... this could go up if you have high ceilings alot of windows,type of exterior structure( example :brick,wood siding,stone,log home etc) and the fact that it is split level would increase it some as well... 250000. not far fetched but sounds a little high unless you have alot of additional factors as mentioned above...hope this helps good luck servicer for 18 years

You seem to know The Mech Code pretty good.
What size LP tank do you have and What size gas

If youy ran a 1/2 line for all three heaters and you have 100lb cylinder of LP gas, it could be the line is to small.

If its happening to all three, i would start there.
