A defective thermostat in your boiler can cause severe damage in your home.
The job of the thermostat is to shut off the system at a preset temperature to prevent overheating. This saves in electrical costs (uneccesary heating) and prevents joints from leaking or bursting from overheating.
We have clients that experienced flooding as a result of forgetting to shut off the boiler.
We recommend always using a timer (have an electrician install one if you don't have one).
We also recommend installing a quality thermostat that is less likely to fail (the blue thermostat in the picture).
Lastly, a thermostatic mixing valve installed on the boiler will ensure that no water above 50C will enter the home, ensuring that no pipes will burst due to overheating.
You may be wondering if adding or replacing defective solar panels for your water boiler is a worthwhile investment.
Budget is tight, replacing the panels is costly, let's cap them off and forget about it.
Well, in the long run that may be a terrible decision. Let's look at the numbers.
Most water boilers have a 2.5KwH heating element. At today's rate that amounts to roughly NIS 1.375 an hour. For larger families that run the boiler for two hours a day, seven days a week, the cost per year is over a thousand shekels!
Within two-three years this family would be seeing a full return on their investment. How many investments see that type of return?
