My original boiler Baxi (for in-floor and domestic hot water) was giving me lots of issues in my triplex here in Toronto and the tech who came to repair it kept saying it was at the end of its life (10 years) and would need to be replaced. So, in April, 2018 when there was another issue I said OK let’s replace it. They said a Navien NHB-110 would be best and quoted me the price.
The install took a long time but when it was finally done, it worked. Domestic hot water was hot and the floors got warm. It was near the end of the heating season however and when it got cold again on November 22, 2018 the boiler got an error code. It took two days before anyone showed up and they took 5 hours to get it working but it failed again the next day. The repair people came several times over the next few days but still the system would only work for a day or two and fail again.
When their expert on boilers finally came, Navien tech support said a setting was wrong on the boiler. They changed it and the system worked for a week until today when both domestic hot water and the in-floor heating both stopped working. I called Cosy around 9:40 AM and they said they’d call back but they haven’t yet.
I called Navien tech support and they were super helpful - after looking at photos of the installation they said it was installed improperly and the piping would have to be redone.
My tenants are understandably very upset and are demanding compensation.
I just heard from them and they are saying that my piping system is wrong. But it worked for ten years and they looked at the piping before installing the current boiler and said that it would work.
