Warmflow Reviews 

Just here as a installer to say I have been fitting Warmflow boilers for 25 years and are my preferred oil boiler choice.
Just a high quality no nonsense heat machine built to last.

Our gshp has failed in May this year after 6.5 year use. Fault was welded on board - manufacturing latent defect - had to pay for a new one £000’s but it was faulty and had to be repaired. Switched on the heating in November and it failed again at start of December. Error message had to be referred to warmflow tech dept who cannot diagnose it but have suggested we spend a further £3.5k with no guarantee that the problem will be fixed. New Parts now also unavailable after such a short time, wonder why? No heating for Christmas. Awful - don’t buy

Just had the annual boiler service in the run up to winter. Superb customer service from Caolán. He arrived on time and completed the job thoroughly. Highly recommend Warmflow. Thank you.

One of the best oil boilers on the market, efficient and dependable.
The professional models are particularly good value for money,
I have installed these boilers for myself, my family members, and numerous customers without encountering any issues that could not be resolved.
Excellent boiler and reliable technical support.

⭐️⭐️⭐️⭐️⭐️

I fit a lot of boilers and have to say Warmflow have impressed me. Solid bit of kit, easy enough to work on, and customers are happy with the efficiency.

Big shout to Andy Bancroft on the sales side – top bloke. Knows his stuff, always at the end of the phone if I need anything, and he actually listens instead of just trying to flog you something. Makes the job a lot easier when the sales guy understands what us installers are dealing with.

All round, good boilers, good back-up, and good people. Can’t fault it. If you’re an installer looking at Warmflow, have a word with Andy – he’ll look after you, he might even fetch some biscuits 😊

The boiler is working well as did the last one. It is neater and very efficient. The installation was fairly straight forward since it was a swap

Had my boiler installed for a few months now. So far so good 👍 no issues. The boiler is smart looking, smaller than my old one, looks well made & put together & comes with all the accessories needed (flume, fittings) at no additional cost. Much better value than Grants prices. I was a bit sceptical at first but seems nothing to worry about. I did want to replace my Grant initially with a newer model, but happy with what my fitter chose.

Excellent boilers and top class after sales service.

Too early to comment really. But anyways, first 3 months are good so far.

The two plumbers who came to do the work were courteous, punctual, and worked very diligently and tidily. They wasted no time in getting the boiler installed.I would highly recommend them

Its a very good boiler

Good system, a couple of minor issues which were promptly resolved during commissioning. Very good service. System performing well.

Delivery on time.

It appears well made and is very quiet. Obviously it’s summer so I’m not using the heating but on the hot water side it seems very efficient

The plumber, hot&cold installed the boiler and it has worked fault less.

We had a new ground source heat pump installed and since installation it hasn't functioned correctly. The noise which is extremely loud through the pipes sounds like a toilet cistern constantly filling. Our old ground source heat pump, whilst almost 20yrs old never made any such noises. The plumber is scheduled to return for a 2nd time after initial commissioning.

Water not as hot as copper cylinder To long to heat up

Great boiler which I fit all the time for my customers,never any issues

Local merchant delivered Warmflow Pro combi to site last Thursday. The merchants driver hadn't lashed the boiler down, it fell over and obviously caused extensive damage to the internals of the boiler. Informed local Warmflow rep. and I was told within 1 hour that a replacement unit was allocated for delivery to me on the Monday, which it was, less damge. Cannot thank Warmflow enough for the prompt response and support I recieved. Thanks again.
