we have had 3 plumbers out to price/advise on the job and all have advised on different methods of plumbing it.
we are now unsure as to whether the stove will be any good and heat the radiators or not and are considering just installing a room heating stove.
Any advice or past experiences much appreciated
If the stove boiler is sized to meet or ideally exceed the heat load then yes it will heat everything fine so long as it's plumbed correctly.
I presume the plumbers advised on the boiler output required to heat your house?
They are plumbed with 1 inch pipes to the hot water cylinder. This is above the stove, so as to get gravity circulation. Ie no pump needed for the hot water side. Our cylinder is 25 feet away from the stove in the loft. It works perfectly. You then use the other 2 pipe outlets (tappings) on the stove to run to the rads. Usually in 3/4 or 1 inch pipe if a very large system. The rad circuit is pumped.
The stove must be installed to an open vented system, ie cold water tank feeding the rads.
A heat leak rad should be installed on the system on large boiler stoves to manufacturers instructions.
The boiler on the reginald is 15kw. If the plumbers advised that your rad output total and hot water requirements were less than 15kw then this stove should heat everything
We have a medium villager Berkley integral boiler stove 7.6kw boiler heating our home. 5 rads and hot water. It works great and we have no oil or gas boiler. We spent 750 euro on coal over 7 months.
