I am installing a whole new heating system and hot water system including new indirect boiler, pipes, radiators and pressurised unvented cylinder (i know this needs testing)
Should the water exiting the boiler go to the hot water cylinder prior to being pumped around the radiators or should it do the radiators first. Alternatively can it go via some radiators to the tank and then via others back to the boiler?
thanks
