Warmflow Reviews 

Being a engineer for 30 years most of the boilers on the market dont seem to make the grade .. 10year Warranty lives up to expectations .. Other boiler manufactures look for excuses not to honor them .. Easy to service and maintain .. Old school oil boiler heavy grade steel .. great boiler you just want something that will last for your customer and cheap easy to service not like a lot of cheaper oil boilers on the market there cheap for a reason .. Mark Hainey is a helpful bloke

Fitting our first Warmflow this week and wanted to gather as much info beforehand as possible, the contact centre and the rep Mark have been easy to contact and really helpful from the start. Mark even came out to the job to go over a few things with the boiler and saved the day bringing a flue along with him for us after a last minute change. First class service all round

Warmflow are the worst quality boilers I’ve ever came across. Every year I experience a variety of failings.

I’m seriously considering a full boiler replacement to remove the problem boiler. The amount of breakdown maintenance required to keep the system working is not acceptable.

I highly recommend you do not buy a Warmflow and invest a little more money on a better quality alternative.

My new heat only oil boiler (replacement for my old boiler which was 24yrs old ) arrived on the day expected and was professionally installed and commissioned after removing old unit first. We have now been using it for a couple of weeks and are very happy with its performance, and looking forward to saving money as it’s much more efficient than the old one.

When I bought my current house it came with a Warmflow Boiler which now has to be well over 25 years old and is still working perfectly. So upon renovating my father's house I chose the same, and couldn't be more please.

Great job, would recommend. Kept well informed, handled all the paperwork for us.

Boiler was fitted as planned. No problems with it and working well.

I've installed quite a few warmflow boilers now, including their internal and external oil combination & system boilers. If I've ever had a installation or commissioning query my calls have always been anserd promptly with great advise.

I've also installed the heat pump system designed by warmflow. Me and the customer are very impressed with how well it heats the property and how easy it is to use, the app that monitors the system is great. And again any time there has been a query I've been given excellent advise and support from start to finish. I have four more heat pump installations booked in they will 100% be warmflow. Great experience all round!

If I could give this company a zero star rating then I would.
I purchased a Warmflow Biomass boiler through MCA Renewables - Glasgow in 2019.
This is my experience of this boiler. It has had a problem since February 2023. It has “exploded” several times with smoke billowing out of it! Regularly the control panel displays “Poor combustion” and there is water inside the ash-pan area. Eventually after several months of emailing the installation company, it was decided that it could be the flue. So this was replaced with a straight shortened flue, (November 2023). The problem persisted. Warmflow eventually sent out an engineer, January 2024, who told me it was just condensation and was normal for the boiler! Really?!
Now they think it MIGHT be some sort of valve that is going to cost me £789.00 plus VAT!
I understand that faults develop and things need to be repaired/replaced but they don’t know what is wrong with this boiler and are guessing! If this doesn’t fix the problem then I can get a credit note back! What for? For the next part that might be causing the problem!
I just want my boiler fixed!

There has been no apology from Warmflow for the inconvience and stress that this has caused me over the last year!

I would not recommend purchasing a Biomass boiler from Warmflow, poor customer service and can’t wait to get rid of it and replace it with something more reliable!

Installed a warmflow boiler just over 4 years ago never had a full year without it breaking down 4th pcb board broken down again no ignition, replaced igniter still not working war.flow says it the photo cell ,replaced that ,now says combustion door open, opened and closed numerous times still tells me door is open ,warmflow very unhelpfully, been on to citizen advice and processed started to have it replaced,we will see how that goes ,next step will be small claims court ,waiting responses from warmflow

Installed an agentis pro 26 combi last week probably the 6th that we’ve installed
Really well made boiler
My customers very happy and comment that they use much less kerosene than they’re previous boiler

Having purchased a Warmflow combi boiler I had it installed by a local heating company.
What a product. ! Using very little oil and house is superb and toasty.

I've just started installing these boilers , they are excellent value for money and with the warranty customers can't go wrong . Warmflow technical support very good

all went well, very impressed with the new boiler

Our previous Warmflow boiler had given sterling service for 15 years until it failed. Our heating engineer,Tripower,installed a new boiler quickly and it has worked perfectly.

Very helpful representative via phone contact. Followed up my query successfully.

Delighted with it so far. Very quiet, clean and efficient.

Serviced a Warmflow Agentis combi, very accessible and easy to take down and clean. Great boiler, no complaints

Oil Boiler Engineers review
Installed a Warmflow i21 Professional today The installation was a breeze.This Boiler had been designed with the installer in mind The Pro version comes with Adey filter and 2 bottles of inhibitor,Fire valve and filter and the condense comes with a flexible connector, again for simple installation This Boiler case is study, not like other manufacturers Along with a great warranty I will fit more of these
