PEX Over Floor - Typlically using ThermalBoard, VersaTherm or Creatherm Radiant Heat Massįor residential slabs we recommend 1/2 Inch PEX tubing to be 12 Inch on center. PEX In Floor - Typlically in poured cement PEX Tubing Under the Floor - Typically under hardwood or tile flooring

Ways to install Radiant PEX with an existing floor Why? Well, because radiant runs at a lower termpeature and this will allow a condensing wall hung boiler to run more efficienty than at higher temperatures.Ĥ. The best boiler for radiant heat is generally a condensing wall hung low mass boiler. Once you have an idea of your requirements, we will be able to get you a quote.

Why? Because windows and doors make a huge difference to the heat load of your home.

We strongly recommend that you download a heat loss calculator. Use the above information to get a rough idea. There are a few ways to calculate heat loss.
This number should be close to the Boilers actual output. This will give you the BTU output at 180 Degrees F. 80 efficiency of your Boiler = 73,000 Btu actual outputĢ) Count the total linear footage of baseboard in the home. Check the rating plate and get the:ġ) For Example -> 92,000 Btu Input of your Hot Water Boiler X. 86 efficiency = 73,000 Btu actual outputĪll hot water boilers sold in the U.S. Factors such as, how long does it take to get to efficiency, condensing, direct vent or not, using pex and amound of water in the boiler all effect true efficiency.Ĩ7,000 Btu input X. Of course, this is a very simple way to look at efficiency - but actually, it is more complicated. An example of a medium efficiency boiler. Then, to calculate the output on a hot water boiler, multiply its efficiency rating by its listed input rating for the actual Btu output of heat. For example, if you live in Zone 3, your home is well insulated, and you have 2000 heated square feet, the equation will look like this:Ģ000 square feet of "Energy Star" grade new construction but with lots of windows = Simply multiply the appropriate factor above by your home's total heated square footage to arrive at your approximate required heating capacity. The Outdoor Design Temperature (ODT), also referred to as the 2.5% design day temperature, is not the coldest day ever, but rather a temperature that is achieved 97.5% of the time. Minneapolis, MN ZONE 4 -> 50 - 60 Btu's per square foot New York, NY ZONE 4 -> 40 - 50 Btu's per square foot Louis, MO ZONE 3 -> 30 - 40 Btu's per square foot Los Angles, CA ZONE 2 -> 25 - 30 Btu's per square foot Houston, TX ZONE 1 -> 15 - 25 Btu's per square foot

Have your architect or builder supply it to you as in many states like NH or CA it is required.Ĭalculate it yourself using software - go back to the Heat Lost Calucator under Pex Tubing Radiant Installs. We are not in the business of selling equipment that you don’t need and a little work up front can save you thousands of dollars in costs over the life of your system.

Oversized heating equipment also often creates uncomfortable and large temperature swings in the house plus it will short cycle the hot water boiler and run outside the design parameters costing you more money. This not only makes the new radiant heating system cost more to install, but also forces it to operate inefficiently, break down more often, and cost more to operate. The most common sizing mistake with in floor heat is in oversizing. Why? Heat loss is a critical step, as we can estimate the average output of a radiant floor at 25 BTU’s per square foot but windows, doors, insulation, and degree days all make a major impact on getting you just what you need. To properly size most components related to your underfloor heating system we highly recommend a heat loss calculation for your project if this is your primary heat source.
