“Rubish”

Written on: 20/10/2014 by Smithek449 (1 review written)

Had it two years and have had 3 breakdowns, valliant call out was rubish always trying to blame old radiators, filter, water quality. They come out take a water sample then leave, still with a broken boiler. Worth spending money on a more reliable alternative. Do not buy… Read Full Review

“Highly dangerous, unreliable boiler, comparable to faeces.”

Written on: 27/07/2013 by Avoidglowworm (1 review written)

My 6 year old Glowworm 24cxi suffers regular error codes and requires resetting at least twice a week. Inlet valve needs to be disassembled after each use in order to reset. Distressingly, inner flue has burnt through. Now requires £350 of spares to achieve safe operation, excluding labour. There is little to love about this boiler, other than the fact I will soon be able to replace it… Read Full Review

“DO NOT FIT A GLOW WORM”

Written on: 22/04/2013

I am a heating engineer. They are so unreliable and have ridiculous parts prices. Bags of poorly designed poor quality rubbish. You have been warned. Just been to a fit a pump to glow worm ultracom, normal cost for pump £100 ish with 20 minute change time. This one £150 for pump and two half hours because isolation valves are cheap and stuck so had to do a full drain down . Absolute garbage… Read Full Review

Have just moved into a rented property which has a Glow-worm 30cxi boiler. We have a payment card meter and seem to be spending a fortune on gas. As you are a heating engineer I was wondering if you could advise me on whether turning off the hot water preheat function would reduce our current running costs?...or maybe there is something else I have set up incorrectly. Would be very grateful for any help you can give - thanks.

“glowworm ultracom 30cxi”

Written on: 31/01/2013

I had my boiler 4 years ago and in all honesty had no trouble with it it was fitted as part of a complete new system which i fitted myself and had a plumber to install the gas as a newbie i took some advise from the plumber who did the gas as to rad size and pipe work runs he recommended this boiler to me and said he rarely fits any other boiler apart from w b the most impressive think i like about this boiler is how flexible the controls are the fact it can be range rated and the fact that its… Read Full Review

“Glow worm ultracom 30cxi”

Written on: 26/09/2012 by Clembo69 (1 review written)

Should have known better, a sensible price at £650 but they get it back on the parts. 2 years and 1 month old the heat exchanger went at a cost of around £270 fitted, another 10 months on and it has decided to spring a leak around the pump but as you can't buy the rubber seal on its own I will have to buy the whole pump assembly for £150ish + fitting. I wonder what is going to fail next I wish I had read some of the reviews on the web before I purchased it and I would have paid another… Read Full Review

Written on: 21/12/2012

My mother has same combi boiler 30cxi & heat exchanger gone twice as fault being hot water running cold. I have a friend who fits them & as a favour had a look & told me that no FILTER had been fitted so the heat exchanger was full of muck which he showed me. Thats why two have gone. He said a filter would only cost about £80. Its only 3 years old so its worth checking this out. Had another fault on fitting as couldn't set the timer & I got them back & apparently hadn't been wired correctly!! The engineer mention Main as one of the best boilers & must admit they seem to last for years in previous properties I've lived in.

“Absolute disgraceful waste of money”

Written on: 01/06/2012

I need to fit three boilers in three different flats over a six month time period. One was a glowworm the others were worcesters. The glow worm has been an absolute nightmare and although only a few years old now I am seriously considering ripping it out and replacing it with a worcester. From a short time after it was installed it hs had constant faults, internal leaks, low pressure, faulty sensors, switches. Every 3 months something new turns up with it. The faults are often so obscure and… Read Full Review

“pump failure”

Written on: 04/01/2012 by mindaugasr (1 review written)

Lasted less then two years.Pump is failing(started running noisy) and I know it will be more to come. The plumber who fitted (now is not answering his phone) said it's the best boiler you can get for £600-700,- Now, after reading trough various treads I can also confirm that this model is RUBBISH. P.S. New pump is on it's way.Costed £160.- Removal and installation is easy so will save on labour by doing it my self(i'm mechanical engineer).Still the quality of this componnent is crappy. … Read Full Review

Written on: 03/02/2011

AVOID. An absolute heap of junk. It breaks down every winter. The hot water flow is pathetic. It takes 30 mins to fill half a bath. The timer has been replaced 4 times, the inlet manifold twice, the expansion tank once and it has flooded the kitchen 3 times. It was faulty straight from the factory and has never worked properly. It is NOT a quality product.

Glow Worm's after sales service is awful. They give you a 2 year guarantee but when it has broken down the quickest they have been out to… Read Full Review

Written on: 15/12/2010

My boiler has some sort of electrical fault causing the fuse to blow time and time again. I contacted Glow Worm, and their modus operandi is to refer you to the technical helpline - which is a Premium Rate number costing 60p/min just to find out if what you believe to be the case is correct which in my case is simply if I just need to arrange for one of the electric components to be replaced and see no more of the electrical fault.

09 number at 60p/min for that? They've got to be having a… Read Full Review

I think you need to have another look at your manual and the certain phone numbers you are calling. Glow Worm's technical helpline is a geographical fixed landline number 01773 828300 this is in no form a premium rate number. I can't stand people quick to shoot their mouth off when they have none of the facts remotely correct. You despise Glow Worm, i despise dim witted people like you.

Glow Worm make it clear that you have to have it serviced by their OWN service engineers for the warranty to be continued. This is an issue alot of people can't seem to get their head around it is simple. 4 pumps in 2 years, Don't you think it may be a rather dirty system instead of 4 faulty pumps...Just a thought

I have fitted loads of these boilers as a plumber ,and very rare do we have any problems with them .A lot of it is down to the installation,a lot of the problems come from not flushing out the system good enough prior to the new boiler being fitted

Written on: 15/09/2009

Glowworm Ultracom 24 cxi Condensing Combi Boiler - My old [10 years]Worcester combi developed a leak which I was informed by a plumber was a common fault with them. I was never happy with it's performance as it took ages for the hot water to get through, plus the flow rate was very poor. After searching through hundreds of different reveiws trying to make a decision on what boiler to replace it with, I couldn't make my mind up. I then decided to leave the choice to the heating engineer, He… Read Full Review
