boiler replacment opinion on the West Coast
I’m a home owner and am looking for some opinions to cross reference the bids of installers. Many seem to steer me to a boiler and tankless water heater. My triangle tube solo boiler for heat and my Takagi 3 tankless water heater for DHW needs to be replaced soon so I’d appreciate some feedback. I live on the coast of San Francisco. My house has staple up floor hydronic heating zones and the walls are insulated with R13 and floors and ceiling at R30. I’ve done a rough total house heat loss calculation of 35K. We have 2 full time residents but run a regularly booked Airbnb frequently with 4 guests
In looking back and with current research it seems my installer did not account for the value of stored thermal mass even though I have a decent size mechanical room.
Now that gas and electricity costs are much higher, I’m thinking of going with a Viessman Vitodens 200 boiler, 80 or 120 gal Vitocell 300 indirect tank for DHW. I’m also considering 2-3 solar thermal panels now or in the future. I'm mainly interested in the Viessman for the integration and ease of installation even though it's more expensive.Any thoughts or advice would be appreciated.

Re: I'm getting solar panels. I'll let you know how it goes in this discussion thread.
Strange how we are using much more electricity than ever before, yet the lights stay on! I guess they are reacting pretty well! Is it possible they might in fact be doing a little proactive planning and engineering?
Re: Trane Air Handler Fan Constantly Running
so you can close the service valves to isolate the condenser then you know if the leak is in the linset or evaporator or the condenser. there is usually a gasketed connection for the txv or a connecting tube with an orifice piston at the inlet of the evaporator. usually inside the casing. do you have specs o the test pressure? if you can increase it to maybe 200 psig or so you may be able to hear it.
