Frost stats

[stratplus]

Hi all, got a boiler in an unheated area with no pipe or frost stat. It's a combi boiler fed from a fused spur with a built in timer and separate room stat. How easy or hard would it be to fit a frost stat to this install?

Thanks in advance?

Hello all, I am after a bit of advice. I have a combi boiler in an unheated area. It has a built in mechanical programmer and a room stat. The boiler is fed from a switched fused spur.
How do I fit a frost stat to this system in laymans terms?

Your boiler may also have dedicated terminals for a frost stat. Need to read the manual.

Energywise would have thought that a stand alone heater on a frost stat would be better.

What is the boiler as some have them built in

I would very much doubt that your boiler doesn't have some inbuilt method for protection against frost.
I would expect that there is a minimum temperature at which the boiler will fire up (usually 4°C).
This will protect the boiler from frost, but might not protect the associated pipework.

Oh right! I will check the manual. The boiler is a Worcester 28 I junior.

Would put in a separate frost and pipe stat as a fail safe, pipe stats wire in series to the frost stat so the boiler doesn't run if the pipes are warm enough, it would need to be put on the return pipe within 600mm from the boiler think the new Worcesters have a frost stat built in them but the old ones from memory don't hope this helps
