I've been installing Warmflow boilers for 19 years. The current range of Agentis boilers are equal to the other two main brand oil boilers. The Warmflow combi is better than the other brands. Its better designed, better made, more economical and easy to install and work on.
Warmflow ASHP are also excellent, so easy to install and very very customer friendly especially when installed with secondary controls.
Warranty are very helpful and friendly on the very rare occasions you need them.
Five star company through and through!

Excellent service from Warmflow

Excellent service from Warmflow. Padraig was very helpful and quickly sourced a slimline indirect stainless steel cylinder I needed urgently.Great quality product and he saved me €400 compared to an alternative brand. Highly recommend.

Does what it says on the tin!

Considerably cheaper than replacing like for like my old Worcester Bosch but this is just as good quality, if not better maybe? Modern design, good quality, affordable and made in the UK too. I really wanted another Worcester but they're more expensive and I simply could not afford to pay for brand recognition, now having done my research, I honestly feel like I've got a reliable bit of kit here when I could have paid a lot more for the same result.

Great Experience

Great support with the product pre and during installation and commission from both Gavin the sales manager and the technical support team (Leo) in head office. I have full confidence in the product which was a Ground Source Heat Pump Cylinder and Buffer tank. Homeowner has never had the system working as efficient or warm with the previous system.

I have been fitting Warmflow boilers…

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.

Good ASHP, but perhaps not right for me

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
