I guess after ten years (wow- where does the time go?!) that you are bound to replace something. We've been really fortunate so far (knock on wood!) that we built a sturdy home and it has served us so well so far.
Bob, a local technician (Landry Home Services) saved the day last winter with some immediate repairs. But in the spring when the heat system died again, it became apparent that there were many parts in the unit that were corroded.
We've been really happy with our decision to use an on-demand water heater for both our domestic hot water and our heating system. On-demand units have certainly become a lot more popular in our region in the past decade and when it became time to choose a new unit, we found we had more options that we hope also come with more reliable service.
Fortunately, we didn't need the heat all summer and that gave us time to shop around for a new unit while we continued to use the domestic hot water supply, which was still operational.
We chose a Rinnai unit that, although it needed some additional parts, basically connects and vents and functions the same so it would be, in many ways, the easiest replacement.
Here's Stach with the old Quietside unit, before he cut it out on Monday.
Stach had already made a couple visits to look at the old setup and measure everything out. He and Bob (Landry Home Services) had also taken a Rinnai workshop at the local supply house (Snow & Jones) over the summer. Stach also started setting up some of the new piping on Monday.
Over the next two days, Bob and Stach worked on installing the new unit and all the new proper connections and valves. Kenny the electrician also came by to check out the job and then to do all the wiring of the new unit.
On Thursday afternoon, with a little programming assistance over the phone from the Rinnai contact person, Stach and Bob fired up the unit! It all works fine.
Bob also fine tuned the efficiency of the burner and printed out a report- 98.1% !! Bob says it's the highest efficiency reading on any unit he's tested. Here's the new unit setup- you can see the report, with some other technical numbers, taped to the front of the unit.
I took my first hot shower with the new unit late this afternoon and it was great! And I never thought I would be so pleased to load up the dishwasher and washing machine with what's piled up over the past couple of days.
The Rinnai unit has a bit larger capacity and more flow power than the Quietside, so I am looking forward to seeing a bit of an improvement on both, esp. since I suspect our Quietside had been incrementally failing over the past couple of years.
Overall, the Rinnai is bigger and needed additional valves and things like an exterior expansion tank, but it also looks a lot sturdier and easier to service, esp. the individual parts within the unit.
Thanks so much to Stach, Bob and Kenneth for all their hard work!
