Good quality combination boiler

[Arborea]

I'm having a new combination boiler installed and the plumber has turned up with a Glowworm Ultimate 3 (we're a small family in a 4 bed, 2 bath 20 year old house).

Apart from the fact that I'm sure we didn't discuss that brand, I'm concerned that it's a bit of a budget brand. I don't mind paying a bit extra for quality, so is there a decent boiler I should be insisting on?

We'll be staying here long term so want to get it right. Previously had a Worcester Bosche in our old house which was great: 8 trouble free years. @PigletJohn any ideas?

The install is next week so I have time!

Just had a new Vaillant fitted and it’s a revelation. All the plumbers we asked to quote recommended Worcester Bosch or Vaillant. Apparently they beat all other brands for energy efficiency by a country mile.

If you were to look at this month's Which, you'd see their top three are Worcester Bosch, Viessmann and Vaillant, scoring 86%, 83% and 80%.

If you look at the manufacturers' websites you may find that some of them give longer warranties if installed by someone on the Approved Installers list.

Glow-worm is described as "average" with a score of 54%

I'm getting a new boiler installed soon. Have chosen a Worcester Bosch

Just out of interest can anyone give he prices they were quoted for installation of these?

I always get Worcester Bosch. Never have any trouble with them.

Thanks all so much, I'll be sending him back to get a Worcester or Vaillant.

Vaillant and Glowworm are the same company. Glowworm is marketed as the lower end.

Worcester Bosch, with all the filters and controls to extend the warranty. WB customer service is amazing. 10 years peace of mind on a boiler in invaluable 😀

We're looking for a new system boiler. One supplier has recommended a Navien (as well as vailliant, Worcester or Viessmann), but all the reviews I can see are rubbish. Does anyone know what which are saying about them???

I've just had my old Worcester combi replaced and all 3 quotes were for the same model of Worcester Bosch and all prices for installation within pounds of each other. It is a fantastic upgrade and am delighted (testing the heating this weekend!)

"Does anyone know what which are saying about them???"

Not listed as far as I can see.

Why wouldn't you get one of their top three brands?

Just wondered what was being said about navien as the bloke was so complimentary about them, but the general reviews were rubbish.

We're getting a Valiant, new hot water tank and Magna Clean for £3,800 with a 10 year warranty

Oops not combination 🤔

We are about to have a new one installed and are probably going to go for a Viessmann Vitoden 100 or an Ideal Vogue C40. There’s only £60 in it. The Viessmann has better reviews but the Vogue has a slighter higher flow rate 🤷‍♀️

Whoever ask about price, I was quoted £2400 and £2340 and this includes a condensing pump and a chemical flush.

The Viessmann 100 is a high-quality boiler, and (if fitted by an approved installer) has a long warranty.

He’s Viessmann accredited and also Which? Trusted something or other! Comes with a 10yr warranty as you’ve mentioned 👍🏻

I've got one.

If you’ve got one and like it then I’m definitely going with that! Is it quiet? We have a system boiler at the moment and it drives me crazy (it doesn’t help that it’s above the living room).

mines a regular boiler (not a combi) so is naturally quieter. It is unusually small so mine fits in a 400mm wide kitchen wall cabinet (mine have 900mm high doors, you might find the flue sticks out of the top) although it is a fake with no top or bottom panel, just a door between the adjacent cabs. The higher power ones are a bit deeper than the less powerful models. Maker's catalogue has the dimensions.
