This is to good to be true. 2 yrs ago I added a 20x20 addition on my home. At that time we laid the pex in the slab for additional heat [ if needed]. Well, we need it, the forced air system just is not enough. The system on page 69 is great. I only have one question . Do you think it can heat and supply hot water to two bathrooms. I must have looked at 100 web sites to find a system like this. Thank you ! Don

ELECTRIC WATER HEATERS WILL SELDOM WORK FOR RADIANT HEAT

Electric water heaters simply do not have enough Btu output for space heating. Remember when you take a shower you are using the stored hot water not the water that it is being heated.
