the conservatory room stat is calling for it? I need to contact the boiler manufacturer to check it will work with another pump in the system. I just don't fancy fitting the electric stuff, not that electrics scare me, I was a spark for 10 years from leaving school. I've read that you have to be careful what you place on the floor i.e. thick rugs, bean bags etc are a no no due to thermal blocking with the electric heating?
No need for two pumps,just add the pipework (in one continuous length,NO
joints) as though you were adding a radiator (which is the continuous pipe),the thermostat for the pipework sits on the lower part of a wall as it exits your conservatory and hooks up with the rest of the CH system.
I installed a system as above in a kitchen extension I built six yrs ago,the boiler is a combi,and the heated floor is in the screed with ceramic tiling on top.
Works like a dream,toasty toes
