When we spec'd out our semi-custom house, we asked for heated master bath and kitchen tile floors.
Well, we got 'em ... but they're only partially heated. The 'design center' assumed that we'd want only 'traffic areas' heated, in both rooms (in truth, we didn't even get that).
It really stinks. Cold feet while doing dishes, cooking standing by the kitchen island, using the toilet (different room, obviously ), etc., etc.
Our builder ... as it has turned out ... really IS a good guy. He's offered to give us "enough $$" to have a hydronic system installed, under the two rooms, using:
- 40 gallon electric water heater
- Taco pump with zone control
- Electric thermostat
- Caleffi manifold components
- Amtrol expansion tank
- Oxygen barrier pex tubing
- Copper manifold components
I have a couple of questions that I'm hoping to get some help with:
- The bid included a caveat, "The floor will only be warm when the system is running. If the thermostat demand has been satisfied, there will be no heat going to the floor." Does that mean it will get significantly cold, and we will clearly feel it cycle?
- The house is a ranch w/a full basement. In this sort of application, is a programmable thermostat a good idea? I know that, in slab-on-grade, it's not advised to use setbacks....
- If there IS a gap between setpoint being achieved, and call for more heat, could the Nuheat system be used to provide bridge heating??
- I assumed the Nuheat system would be fairly bulletproof and very long lasting. Are there significant lifespan and/or maintenance requirements and/or $$ for the hydronic system (eg, It seems that glycol has to be checked annually, and additives may have to be added, etc.)
- Is it common/normal/alright to use what seems to be a standard residential water heater to support such a system? We're looking at heating a 17x11 kitchen and a 10x10 master bath.
- Any other thoughts on this switch-over??
I'd be grateful for the help.....
