Warmflow Reviews 

My experience with warmflow was really great. I was well informed with what needed to be done and there was always someone for advice. They helped me get my heating upgraded. You do need to source your own trades people.

This was the company that our plumber had used in the past. Great boiler and have had no problems with it.

I have been fitting Warmflow boilers now for around 8 months and I am very happy with them. There is alot of stigma relating to the brand from many years ago, when I was an apprentice (20+years) we fitted one and I was not overly taken by them and since then used another big oil boiler manufacturer. I was in a bit of a muddle last year needing an oil boiler for a specific job which my usual oil manufacturer would not give me warranty on if installed, I spoke to my Warmflow rep of whom I know very well and he sorted this for me and they were happy for me to use their boiler with my specific site requirements. I was shocked to see how much they had changed and this boiler is well built and very nicely laid out using quality parts and came in many different options to suit your needs. You can get a 5/10 year warranty if using a pro installer and in my honest opinion a very good company to deal with and should you be unlucky to encounter a problem somone is at hand to assist. I will be continuing to fit these boilers, cylinders and now heat pumps.

Very good boiler. It's quiet and uses less oil than the old one

I feel a bit bad giving only 3 stars. In the main, I feel that my installer didn't listen to my requirements and perhaps I should have asked more questions upfront. My installer turned out to be a cowboy who tried to rip us off at every turn, none of this is Warmflow's responsibility. But I asked for an ASHP that could be configured and integrated into my home automation set up. I was assured it would. This was not true. The ASHP itself works just fine. It heats the house and the hot water. It is quiet and efficient to run. In addition, due to the poor quality installation I had to contact Warmflow support on several occasions. Each time they were pleasant, helpful and easy to deal with.
My biggest issue is with the front end. Both the panel on my wall and the app are not very user friendly. I would like to tweak the AT curve in response to real-life experience, I can't figure out how to do that. The app feels very unintuitive and under-developed.
If you've got a good installer who is going to set it all up for you and then you want to set and forget, then I think Warmflow would meet your needs. And I would be re-assured by the quality of customer support available. If, however, you want to tweak the ASHP post-install to try and truly optimise the efficiency of the unit, then this might not be the best choice. Nothing at all wrong with the product, but not the best fit for every user.

[EDIT] I note the comments provided by Warmlink, in particular, the mention of 3rd party front-ends. Would Warmlink be able to provide some examples of front ends that can work with the AS03-R290? It would be appreciated. Thanks

Good value for money and highly recommend by our plumber Phil.

soo much improved heat in our home

Made my house a lot warmer

Only a boiler purchase all good

Installed for some months now all working well

It's clean, functioning, reliable, quiet and makes a world of difference compared to my old noisy boiler which kept needing maintenance

The oil burner is the most efficient system we have ever had installed. Also seemed easy to fit & looks neat & tidy.

Thank you for a brilliant heating system.Have been lovely and warm all winter.Cathal and his crew where very efficient installing the system.

Working fine now but needed a separate thermostat as supplied one doesnt work. Told that this is a known issue and not just a one off.

I can't recommend these boilers and heat pumps enough my customers with the heat pumps say they love them I've changed 2 heat pumps 1 LG and 1 vailent to the new warmflow R290 heat pumps and they said the cost to run has halved both customers and the boilers I use to fit alot of Grant and Navien until a few problems with navien and Grant cost just keeps going up admittedly the early warmflow boilers I would not touch but the new Agentis Range I won't fit anything else they are truly an awesome bit of kit I've fitted about 10 up to now

Great boiler, fast heating

Fabulous efficient boiler, has made such a difference to the house.

Really excellent boiler - oil fired combi. saves us a fortune on electric heating. It's fast, easy to configure and looks very solidly built. My only minor criticism is that the exhaust is a bit louder than I expected.

Everything has been so easy to use. From scheduling to knowing room temperature. I can adjust schedules very quickly and boost when needed.
