Wireless room thermostat advice please

True, but any heat loss from a hot tank goes to heat the house first and is not not lost directly. So, as you say, it's negligible.

Leave the Potterton alone - keep it if possible- much more reliable than modern condensing boilers.

This is a netaheat 10/16, not sure if the mk2 or the electronic but both were well known and nicknamed 'the widowmaker'. They were one of the first positive pressure fan flued boilers and suffered from rotting cases and plenty of carbon monoxide incidents. They have very few parts available for repair and the last 30 years of use will have the heat exchanger banging and clattering away. These things need chucking out asap.

Your link is accurate but doesn't point out any benefits to replacement.

A typical scaremongering reply from a BG employee (why do you not declare your interest when posting on the forum?).

The OP will soon regret replacing a perfectly good working boiler, which most likely has many more years life in it before it actually needs to be scrapped.

Ok, I started looking at 24kw models e.g. Worcester 24i, then updated to 28kw after reading about the low flow rate of the former. Which model and brand of boiler do you have and what is your honest opinion of it?

Vaillant ecotec plus 831. So far so good. Plenty of hot water and the flow or temperature isn't affected when water is drawn from another source such as washing machine or toilet.

My parents are renovating a house, the heating has just been completed and unbeknown to me their plumber has also recommended and fitted the same boiler.

Please, if it's typical, show me a huge selection. I have no interest in what the op does or doesn't do but I can speak from a position of knowledge and experience on the subject.

I am overjoyed that your knowledge of this boiler exceeds and over-rides the safety notices issued by the hse and manufacturer and will now of course keep my opinions to myself.

I agree - so if I wanted to keep this, what are my options acknowledging that I need to free up the airing cupboard space?

Thanks, I will research this range - but the 7 year guarantee T&Cs worry me, please see my previous post.

no need to fight guys, I've already learned that asking the question "which boiler should I buy" is like asking "which car should I buy", it's obviously going to depend on your requirements and your preferences and also your own experience with brands etc.

It's just that I initially assumed I would HAVE to get a combi in order to free up the space and when I told the two RGIs about my requirement (to install a separate WC in the house) they both recommended I switch over to a combi boiler and remove all the tanks from the loft and the cylinder from the airing cupboard.

Appreciate all the advice and pointers - and I am still researching!
Thank you

Ours is a five year guarantee and has no such restriction. To be honest it wouldn't bother me if it wasn't transferable. Once a house is sold the boiler is the new owners problem, not yours.

Every year thousands of homes are sold with boilers which won't have a warranty.

As ours is a relatively recent installation I may even call Vaillant and try and get our warranty extended to 7 years!
