Hello,
We just got a new heating system installed, its called a sealed system i think?? but we have to valves marked "CH" and "HW" but in the hot water tank in the cupboard is only a coil inside the tank i assume is it?
what does the "HW" switch on the programmer do when it is switched on and the "CH" is off, i thought the "CH" switch had to be on for it to heat up the tank with coil being on the with radiators is that correct??
I aint a plumber expert just was wondering how it worked, also the boiler only two pipes coming out of it so didnt know how it worked?
Any help would be nice.
Thanks.
