How did the conversion go? We have 8mm pipe and considering the same

Yeah it would bug me too . We’re now considering a regular boiler instead of a combi so maybe won’t be an issue after all

Hmm Hive themselves said it's no problem.... is it best to buy a new one?

I do like this idea because it's risk free (we have old 8mm microbore so I understand there's a risk going pressurised?). We also have the space already (big huge water tanks in loft + a cylinder in the airing cupboard) however... the small amount saved (£500) on a standard boiler is outdone...

This would cost a lot more though so maybe that's why combis are popular. It's my understanding that we could stick with a standard boiler but we'd need a new hot water new cylinder with it and we'd also need some kind of shower pump or digital shower installing to get something workable...

As mentioned earlier in the thread, everyone offers something different. One offered a System boiler + unvented tank, but another says we don't have the water pressure for that. It was £1500 more anyway so not a goer for us.

No dynamic readings given. We have 1 bath, 2 showers, 15 rads. The whole experience of getting a boiler has been frustrating, mainly becasue every man and his dog seem to advise something diferent and it's hard for a layman to know what's best. We've had it all. Re flow rates, we used...

The cylinder is 35 years old, same as the current boiler. static 12.5L/min and 1.8 Bar is from one of the very respected local plumbing firms who quoted us for a 40kw Combi. The 6 L/min (tap) and 3L/min (shower) were measured by me basically filling up 1 Litre several times.These are upstairs...

I agree. What I can't understand is how good or bad it is in practice. Clearly the plumbers quoting only care if it makes water hot, but we obviously want to improve what we have and be trouble free. Happy to wait 15-20 mins to run a bath (better than waiting an hour to re-fill a cylinder). For...

Waste of money in terms of upfront costs or running costs? We're only being offered 35 unfortunately. Advice is so conflicting - we've had quotes saying 30kw is right and others saying 40! Some say our water is perfect others that we need to spend on increasing the flow and digging up our...

Thanks, I mean the Hive 2.0 thermostat as opposed to the original V1 model.

We have a standard boiler and a Hive 2.0 + Hub wired up. However, we are switching to a combi, will this still work or can it be easily adapted by the plumber; or are we having to buy a new one?

Vaillant ecoFIT pure 35kW

1.8 Bar Standing Pressure - 12.5 Litres Per Minute. Conflicting advice whether this is OK for a combi boiler.

We have gravity fed system and awful shower pressure. We really want this rectified but unsure of the best option. I am thinking either a shower pump or a couple of digital pumped showers. Does anyone have any experience with these two? Partoicually interested in the amount of mess / upheaval...

I will. The company doing it (Heatable) says it's no problem but I will reinforce my concerns with the actual installer.

Pretty sure it's 8mm

eek! what kind of things shall I be looking out for?

The work hasn't been done yet - we are having a new boiler installed next week and this is part of the job. I am just trying to get ahead of any issues. The system has never been cleaned to my knowledge and is about 32 years old!! We are having a magnet filter applied with the boiler. The...
