I'm having a new CH/HW system installed from scratch (to replace a somewhat antique, expensive and broken warm air/gravity system). Our chosen plumber has recommended:
Vaillant Ecotec 630 condensing boiler Santon Premier Plus unvented pressurized cylinder
15 radiators for a 5-bed house.He seems to be competent, but any comments would be appreciated. Is mains pressure HW the way to go? (We already have a CW tank in the loft, which would go.)
I am particularly interested in the safety and servicing requirements of unvented systems.
We already have a shower pump fitted in one of the bathrooms. Is this permitted under the bye-law that prevents pumping from mains pressure systems, or does that only apply to combi systems?
thanks, Andrew.
