We're having the whole lot stripped out - want one that isn't 30 years
old and badly insulated for the new boiler - and the installer has

warranty is longer!
What do the team think?

Depends on your mains pressure and flow.

On the upside
- no loft tanks
- mains pressure hot water for showers

On the downside
- higher initial cost
- requires annual safety check
- requires tundisk and pressure relief pipework
- may also require pressure regulating valve and pressure relief valve on the cold mains inlet as well


What does the annual safety check entail?
