Unvented cylinder size

[EvilDrPorkChop]

I have 170l on HW Priority and well, it's not enough (Cylinder was existing in house when we bought). 2 People at 20lpm showers. It reheats rapid (Maybe like 10 minutes), but personally if you've got the physical room i'd go with a minimum of 250l. Especially in a 4 bed house.

You don't need fancy controls. You can do it quite simply with a relay that costs £15.

How many bathrooms?

If 1, another option is to put in a plate heat exchange and go instantaneous with no store of hot water...

1 bath, 1 ensuite, maybe a 2nd ensuite at some point...
Bungalow, so head height is an issue...hww pressure is poor

Definitely 200+ then. As I said i'd go 250l.

I often spec for 'Gledhill platinum stainless indirect' cylinders. I rate them and they have the floating baffle that eliminates need for expansion vessel and adds a decent amount of accumulation that may help with your 'pressure' issues

No go for the plate heat exchanger with your current sized boiler.

330i is a rebadged Glowmorm boiler so she's getting on a bit now probably over ten years or more but if well maintained and serviced I'd connect to a unvented cylinder or you may want to consider a boiler upgrade at the same time , but as Timmy has said not suitable for a plate heat install as it is .

Yeah, thats the one, it still works and gives us heat! Its bastard expensive to run mind...
Im not against upgrading it, but i need to justify the cost against the working unit tbh...

Water softners a thing to look at....? Whats the best thing without spending a million bucks....

Never had a problem with Monarch water softeners and reasonably priced , I'd maybe think hard and get both boiler and cylinder done fit weather compensation is a must now to save energy. Kop
