Grant UK レビュー 

The installation engineers were brilliant - working on a difficult job in hot weather to get a really good job completed

The boiler i have installed is very efficient

Installation was quickly carried out

Very pleased with my new condensing boiler. Installation done in one day and it has additional features compared to with my 20 year old one. Still to see if it proves to be more efficient. Thanks

Good installer no problems so far with the ASHP.

Every year something will go wrong with my Grant Vortex oil boiler even if It has been installed and serviced by a Grant approved installer. Basically, they are of such poor quality something will fail, without a doubt, at least once a year. Over 6 years, 4 new expansions tanks, two pumps, leaking manifold, two switches "on-off", leaking oil pump, Perished O-rings, although I think I was conned there as nitrile o rings last for 20 years so lets put that down to service engineer bullsh*t to make money. Grant approved installers and service engineers, what can I say!! The first two years, absolutely perfect, changed engineers, in and out in 20 minutes, did not clean baffles or tubulars, said it wasn't necessary if the fuel mix was set correctly, condensate trap was left filthy, oil leaking from the pump "forgot to tighten the bleed screw and claimed the O-ring was perished!! A nitrile O-ring submerged in oil has a service life of 20 years. I am not a mug, I have a degree in mechanical and Aeronautical engineering with heat exchange being one of my specialities, just because I have grey hair does not make me believe the shyte you are peddling.
So, as I sit her tonight with water pouring out of the back of the boiler and having to wait a week for a engineer "probably another failed jacket" No hot water, as the vented immersion element was never checked to be working, and it doesn't. I was wondering if Worcester is a better alternative!
@Grant, your product quality leaves a lot to be desired, your "approved service engineers" not all of them, but 3 out of 5 in my experience are useless.
Should we buy your product again? and by we I mean 3 households on the same farm with the same problems, I don't think so.

From the moment of fire-up, it has been exemplary.

My husband installed vortex boiler house in May. We had a very old Worcester that had done it's time. Stripped of parts that were new to use with boiler house. Once installed and tuned in, it has been purring like a kitten. Sweet as a cherry. Definitely cheaper and more efficient than older boilers and farrrrr more efficient than our air source heat pump. Let's hope oil will be around for a very long time.

Installation has only just been completed so it will remain to be seen how efficient or cost effective it will be - fingers crossed! But, the team working here, the plumbers, the electricians etc have been terrific. They have worked so hard and so efficiently. Fantastic 😀

UPDATE:
After leaving a negative review Grant UK contacted me within hours. I am extremely happy to say that they made a full refund of the parts we had already purchased without any unpleasantness. How refreshing to deal with a UK Manufacturing company who value their customers.

Purchased Vortex Blue condensing oil boiler in 2022 the solenoid has failed boiler won't start without it. After engineer has investigated to find out the blue burner has been discontinued. We have been advised to replace with yellow.
They obviously knew there was a problem but failed to inform their customers. If this was a car there would be a CALL BACK. We are now stuck with a three year old burner that is not worth repairing.
AVOID AT ALL COSTS :(

Really efficient oil combie boiler very pleased with performance quality and instilation by south hams heating thank you.

Installed by Robert Hughes and his brilliant team. Totally satisfied.

This is the first time I’ve had an air source heat pump (inherited from a house purchase and the previous owner Installation).
I was not used to this kind of system, having always had gas provision and there were some things which seemed a little bit strange to me in the configuration of installation.
I called the technical helpline where I encountered Josh. I have to say that without doubt he is one of the most helpful people I have ever encountered in any transaction. He asked for some photographs to understand the installation and immediately recognised what was going on in the system. From there on he was able to make some constructive ideas to consider in terms of potential changes, with a realistic approach of whether they may actually improve the system. He instilled such a confidence in me that since my previous query, I was able to contact him with yet again, a real can-do attitude and his recollection even of my system configuration absolutely impressed me when he’s probably speaking to lots and lots of customers.
I have absolute confidence, not only in Grant UK, as a result of my dealings alone with Josh but in the product itself in terms of reliability and longevity. So essentially, I’m a very happy customer and wholeheartedly would recommend my experience.

Outside oil boiler running great. No problems.

A lot more efficient than the last boiler.

I have a grant R290 9kw unit fitted with smart controller and room sensor.. so far it’s been excellent.. high performance, fast response, very effective.

Early days with our heat pump but good so far. Pump itself is compact and very quiet. System seems efficient but yet to be tested in colder weather for the adequacy of the temperature. Installation went well and all the team were hard-working, diligent and considerate. Process of survey and funding was good and presented no issues for us. On current experience, would recommend both the kit and the installers.

Boiler installation relatively smooth, nice and quite, water boiling hot. Easy to register, swift response from companu.

VTX PRO 26/46 installed last week by HQ Plumbing & Heating Services Ltd. Great support throughout the decision to change the heating system, including oil tank selection/installation. Professional from start to finish.

Efficient and professional engineers fitted the boiler in three days and the job they did was very good. I am very pleased.
