Cost Saving?

hr

propane water heater does not have a lot of features as far as conrols. It turns on and off based on tank temperature. It is not easy, or even possible to safely add reset controls.

With the cost of energy they may want to consider upgrading to a high efficiency modulating boiler. Most have weather responsive controls built into them. This would further increase fuel savings.

Basic tank type water heaters are on the low end of the efficiency scale.

Cost Saving?

Hey guys,

A user on our forum posted this question which I have no idea on:

We have had propane heated water radiant heat in our floors for several years. In the winter we set the heat at around 70 and leave it at that level all the time due to our idea that it may be inneficient to turn the heat down at night, back up in the morning and down again while we are at work? We were told that it can't react quickly. What is the most efficient way to set the tempeture and how much can we vary it in order to save on fuel costs?

Apart from reducing the overall temperature I'm not sure what to suggest to her.

When we used to carry Trimatik MC controls

we worked with around 7F degree night setback. This seemed to improve night time comfort and gave good morning recovery to boot.

One of the benefits of radiant heat is that many find it more comfortable at lower space temperatures than any other form of heat.

While tastes and comfort levels certainly vary, 70° sounds a bit high. I honestly believe that many people are "programmed" for 70°-72° thermostat settings. If they see lower they think "I must be cold".

A simple experiment is to put black tape over the thermostat setting and room temp display, remove all thermometers from the house and move the t-stat setting down a tiny bit every 2-3 of days until you actually feel too cool. Then move up a tiny bit once or twice. Then remove the tape and see your actual "comfort" setting.
