I had a Worcester Bosch 38 Cdi fitted last week to replace my unreliable Ariston 24 MFFI.
£1970+Vat

I had kept the Ariston going for quite a few years and parts were still readily available (and cheap) but it just simply never had adequate DHW even with me cleaning the scale out of the DHW heat exchanger annually. Things improved slightly when I fitted a combi-save but it just took too long to fill a bath.

I went for the add on magnetic filter and hence got the 10 year warranty on the Worcester
I also bought the matching timer and wireless remote thermostat
The comparative increase in DHW output is most impressive running 2 showers now is not a problem
Water can now be 'ouch' hot.
The Worcester is a lot smaller than the Ariston and considerably quieter.

I did toy with the idea of going for a system boiler and installing a direct twin coil (for solar) cylinder but decided against it simply because the Feed in Tariff for solar HW does not offer a good return.

Might DIY as system one day though using old radiators as collectors.

I also have looked, on and off, for years at both air and ground source Heatpumps.
I have enough land to install the loop but again the initial cost is very steep plus I would have to up size all may rads to allow for running at 55-60 degrees instead of 70-80

Well this is it - plumber says we have 12 bar coming into the house

I like the look of these personally

Well this is it - plumber says we have 12 bar coming into the house so cannot put a pump on it to increase pressure but as soon as you turn on any tap whilst shower is on shower loses power...

oh well thinking of getting a gravity fed tank to sort out upstairs shower

if you have a combi system you can`t put a pump anyway because it is mains fed

you will lose some power when turning the tap on , but should still be usable .

if its an old boiler i would go to a system boiler and a megaflow , although you can use combi boilers to feed megaflows .

a good indicator is filling a 10 litre bucket and timing how long it takes

depends on the flow rate of the boiler , is the garden tap or kitchen tap high pressure

electric showers are shi*e anyway

It's a combo boiler

Downstairs shower is just direct from the pipes upstairs one is an electric one

not gravity fed - boiler is downstairs

what is it system or combi boiler pressuried cylinder or gravity fed ??

Need to replace my 30 year old boiler.

I regularly trade down to an 18 year old.

I always struggle with getting two showers to work at once

and the plumber said we have 12 bar coming in....

does a system with this many showers need to be gravity fed?

Need to replace my 30 year old boiler. 18 rads in the house and 5 showers so need a decent boiler and might as well get some nice gadgets for fun.

Am looking at something like the Vaillant 418 with their vSmart remote control tech. Boiler is around £850 then fitting etc on top, hopefully all for under £2k.

Anyone here been through a boiler selection process recently and can advise?

Wouldn't you be better off getting a single heavy duty boiler for the whole house, rather than a separate one for the annex?

Many thanks! The front door key is in one of the strawberry pots

Don't worry. She gave me the key to her the backdoor

Worcester all the way - they just work!

Let the engineer size up the radiators etc and assess the correct one.

One thing - they needed to install a new gas pipe to the boiler from the mains as new boilers need a much wider mains feed pipe as they blast in gas at a greater pressure which makes them more efficient.
