How do frost stats work

This doesn't mean you have to keep your house as warm as normal — any temperature 55 degrees or higher is appropriate to keep your pipes safe. What temperature do pipes freeze in a house UK? There is no simple answer. Water freezes at 32 degrees Fahrenheit, but indoor pipes are somewhat protected from outdoor temperature extremes, even in unheated areas of the house like in the attic or garage.

Just because it's 32 degrees outside doesn't mean the pipes will reach those temperatures. What is hive frost protection? You can activate 'Frost Protection' by turning your heating to 'Off' on the Hive app, or the thermostat.

Do boilers have thermostats? Boiler thermostats and central heating controls not only make it easier to utilise your boiler, they can also reduce your energy bills dramatically. Plus, time and temperature controls are also now an essential part of a central heating system under the Boiler Plus legislation.

What is a Frostat? Can a combi boiler be fitted in a garage? Yes a combi can be fitted in a solid brick construction garage, but bear in mind that any susceptible frost damage pipework must be protected by well insulating it! What is a pipe stat? A wall 'stat better monitors the general environment around the boiler. The wall 'stat turns the boiler on when the air temperature drops low enough for freezing to be a hazard.

Once the heating pump starts, the pipe 'stat more accurately reflects the temperatures in the whole system. How do you wire frost stats? This video covers wiring for frost thermostats on S plan, Y plan and combination boilers.

View on Youtube. Two thermostats are used, the first being an air sensing thermostat. This should be installed in the coolest part of the building, typically on the ground floor. If parts of the heating system extend to areas likely to be much colder such as garages or conservatories, the thermostat should be installed there. This thermostat activates when the air temperature falls, typically below 5C.

A second thermostat is installed on the heating return pipe at the boiler. This activates below about 30C. However any frost thermostat that can be set to 5C and a pipe thermostat with a range of about 10CC could be used.

A single air thermostat would work, however that would use significant amounts of fuel as the air temperature would need to rise above 5C. That would require the boiler to run for much longer and heat the radiators to a much higher temperature.

Although not shown in the diagrams, the cable to each thermostat would normally be 3 core, the 3rd core being used as the circuit protective conductor earth. The objective here is to connect the permanent line terminal 1 to the heating on terminal 5.

This will activate the heating regardless of any other controls. Reply to DaveA. Notify me about replies to my post Post Reply. David Hearn Contact options for registered users. Show Quoted Text.
