I have the same issue, only two black wires coming from the

Hi Tom,I have the same issue, only two black wires coming from the wall to the thermostat. I disconnected the old thermostat (the type with the pill shaped Mercury capsule) and connected a new basic Honeywell. (The old thermostat did not have labels for the wires, so I connected (at random) to Rh & W (Rh has a jumper to Rc, which I left). Upon turning the power back on and turning the heat right up, nothing happened. I switched the power back off and swapped the wires thinking maybe I'd mis-installed. Still no heat. Any suggestions?

We have an Alpine Gas-fired hot water boiler (model#

We have an Alpine Gas-fired hot water boiler (model# *****), installed in 2009. On attempting to do the annual inspection, the technician found a stripped screw on the heat exchanger and refused to do any inspection pending replacement of the heat exchanger. Is the heat exchanger needing to be replaced? The unit continues to work without fail over the past 4 months. The heating and plumbing company is hedging on the price of the replacement with a rough labor cost of $2000 plus the heat exchanger.As this company installed the unit, it was best thought to use them. But if this is a straight forward repair, the home warranty company has their local contractor who is willing to do the replacement at a lesser cost.Can we risk running with the unit until it breaks?

I have a 4-unit apt. bldg with 4 small Raypac boilers

I have a 4-unit apt. bldg with 4 small Raypac boilers (H4-0042). The system was installed with 1 pressure reducing valve (PVR) for the 4-unit system. A repair company recently advised that the system should be reconfigured to install a PRV for each boiler. The job would be expensive ($3000), primarily to reconfigure the piping.Do I need 4 PVRs?

hello, i have a honeywell t8085a with q682b subbase controlling an electric air handler and separate gas boiler heat circuit. I have 6 wires, one is r/w/g/y and the other is r/w. they landed on c/c/r/w/y with a jumper in the mix some where, didn't see it hooked up on the thermostat. I am replacing this t8085a with a honeywell rthl2510c and am not sure how to land these wires to the terminal block. it is as i said an 240v electric air handler with a separate circuit 240v gas boiler pump heat and 120v fan switch, separate circuit.
