Hi,
I have a
1) Crown Mega Stor Indirect Water Heater model #MS-40, Capacity: 40 gallons, Max Allowable Working Pressure: 150 psi, Temperature set to 170°, Watts Regulator Temperature & Pressure Relief Valve Model 100XL, Honeywell Aquastat 8148E Controller, Type L4006, Watts Regulator Expansion Tank, Model DET-12 M1, tank volume 4.5 gallons, and
2) Crown Boiler Model XBF-150EID LP, Input 140,000 BTU/hr, Maximum WP 30 psi, Minimum Relief Valve Capacity 118 lb/hr or MBM, Temperature & Pressure Relief Valve Watts Regulator Model M3, Effikal International Flue Damper Model RVGP-KSF, unknown brand expansion tank
The boiler supplies the hot water for both domestic purposes and radiant in-floor heat.
The issue: sometimes we have domestic hot water and sometimes we don't. One plumber we have hired in the past said he had no clue what was wrong. Another plumber came up this past Friday, listened to my description of the problem and using only his eyes, no meters, no tools, nothing, pointed to the transformer on the Aquastat, said that was the problem, as the transformer was getting weak. He would have to have another plumber in his company come up to make the change and that cannot happen until next Tuesday, Sep 17. Ugh...we wanted it fixed sooner than that. We get hot water by manually propping open the switching relay on the Aquastat and my wife is tired of waking up in the morning to take her shower and maybe having hot water.
The questions:
1) Can a transformer get weak and only work some of the time, causing this problem?
2) Can I replace only the transformer or does the entire Aquastat need replacing? At about $180 for the Aquastat it seems kind of expensive if the only thing wrong with it is a transformer, which appears to look like many other transformers.
Thanks.
PS.
There are 6 zones to the radiant in-floor heating system:5 have been there since 2001, 1 added earlier this year by a plumber but is not active...
