Hi All,

I have a 20 year old house that has one of these beasties. Due to it's age and the fact that we are replacing each of the bathroom suites, I think it is time to look for a replacement. I'd like to increase the water pressure at the same time, so that we can choose high pressure taps/shower heads...

Does anyone have any knowledge/experience of newer versions of these?

Would I need to have a pump in order to improve water pressure, or do they have these built in now?

Thanks in advance.

Unvented system would be best. Higher flow rates for efficient hot water delivery (Up to 72 l/min) High performance showering –throughout the home Fast-filling baths Quieter mains pressure system (no noisy cistern in the loft) Fast recover rates (eg. 15 minutes for CL125HE)
Do you have good mains pressure to the house? If you install a pump you will still need a tank in your loft. Are you thinking full house pump or 1 in each bathroom?

The mains pressure is good, I'd rather have a 'whole house' pump if required, than four seperate ones.

Er, am I missing something or are you talking about something completely different to what the OP asked for....?

I speced some of these last year for a school. Great bit of kit, probably useable in a domestic situation.

Excellent, thanks. Do you know what is meant by 'fully room-sealed'?

A room sealed boiler (fully room sealed), the flue is sealed from the room, and all air for combustion is taken from the boiler position outside the property.
