Hi,
My heating engineer has installed a new heating system with underfloor heating, it basically consists of:
grant condensing outdoor oil bolier.
range unvented tank
underfloor heating
gundfos UPS pump
existing Radiators in all rooms except kitchen.
new kitchen has UFH, this is an LK system with mini manifold and its own pump. This is connected to the boiler primaries
There are three 2-way valves - one for heating(radiators) , one for water and one for the UFH.
There are 3 controllers, one for UFH, one for heating, one for water, each is totally independent, each will turn on the associated 2-way valve and also turn on BOTH the boiler and the pump.
What I am concerned about is if the UFH is on while both water and rads are off...
There is no bypass loop, so when they are off the outlet from the main pump is effectively shut off. The pump makes a slightly odd noise because it can't pump anywhere.
My heating engineer says this is O.K and that the pump will not burn out.
I am dubious, I think it needs a bypass loop or a system using relays so that the UFH controller is able to just turn on the boiler and not the main pump.
Any advice would be most appreciated.
