If I turn it down to 55 the place will take all day to get back up to 68, just not happening here.
No idea but whatever you do try to do it far enough away from the wall to leave plenty of room for a coupler if needed.
Aren't you only supposed to deviate temps by like 7 degrees or something or it starts becoming more costly to reheat the home than you saved by cranking it down?
55 at night, 63 during the day, always warmer than that because we assist with a wood stove. The stove keeps the part of the house that we use most (dining, kitchen, and family rooms) very warm. Bedrooms, basement, living room, and so forth stay cold. It not only saves money, it keeps my family in the room together rather than languishing alone in their rooms. Nice side bonus.
Thermo-dynamically that doesn't really make sense. The cooler your house is, the less heat loss there is. So the cooler the average temperature of your house, the less energy you're going to use. It might take more energy to go from the setback to the normal temperature, but that would be more than offset by the reduced consumption when it's set back. I'd say the main concern with having a setback of more than half a dozen degrees F or so is that depending on the weather and how your heating system is sized relative to the structure's heat loss, it could well take hours for the house to become comfortable again.
It really depends on how close the tankless heater is to your faucets, and how things are piped in your house. The heaters really are near instantaneous in terms of heating water. The problem with delays is due to the piping between the heater and the faucet. If it's on the far side of the house from your kitchen and there's a big 1" line that feeds most of your house that needs to have the cool, stagnant water cleared out first, it's going to take a long time before the water coming out of the faucet is warm. Again, depending how the water is piped in your house, you could potentially add a recirculation pump that will continually keep the water moving and warm. That of course comes with an energy cost both to run the pump (it should be tiny, but it's running all the time, or perhaps on a timer, so it adds up) and increased energy consumption of the heater as it will periodically turn on to keep the temperature up.Qerero_sl said:
Yeah thanks, makes sense. The heater is in the basement and while the house isn't huge I can believe that the piping is not ideal for the tankless system. The shower seems fastest, which makes sense given what you said about clearing the cold water out first.
