1 Answer

Most economical use of heating

We have just had a honeywell programmable room thermostat fittd with our new bolier. Could anyone advise me what is the most economical way to use it please? We're out at work from 7.30am and get back about 3 so the heating doesn't need to be on all the time. It has 6 settings and I only need to use 2 in the morning and 2 in the afternoon/evening. (On & Off times)but I'm not sure what to do. I would really appreciate some help

There should be "how to"program instructions with the new thermostat. If you had this professionally installed... the tech should have set it for you. All T/stats are different. I suggest that you "do not" set the temperature up or down more than 4-5 degrees. If you go back more than this you are defeating the purpose of the program. Yes you will save $$$ when it is set down to a lower temp. BUT.... when you turn it "back up"... not only are you heating up the ambient air in the house that you lowered. You are also heating up the couch, the walls, the drapes, the table, ect . this can possibly use back up all that you saved and then some!
I am a retired heating contractor. I have been in the business since 1977. I now teach heating and cooling to high school students at a career center. I have experimented with most thermostats at my own home. I want to know them before I would sell them. From my own experience I found that the most economical savings is to find a comfortable temp and leave it alone. It is cheaper to maintain a constant temp then to keep playing with it.

make sure it is not telling you room temp, some of the Honeywells, will display room temp over desired temp. check that, if it wont let you switch temp than buy a new one, if you dont have a heat pump a new cheap stat is around 20.00.
