I have a Buderus SST300-80 indirect water heater and notice

Good morning,I have a Buderus SST300-80 indirect water heater and notice that during the summer months when we have higher than normal humidity, there is water that leaks out of the bottom of the unit. The heater is only 4 years old and this doesn't occur during the other months of the year. Has anyone ever experienced anything like this and what would cause this? I can send a picture of this if you let me know to what email address.Thank you,Vin

After nearly having my home destroyed by inept plumbers and

Good afternoon,After nearly having my home destroyed by inept plumbers and bad hydrostat controls and a second set of controls and chinese gauges that are also being sent back to the retailer I am replacing them with honeywell controls and A brand new Mashalltown triple gauge.The boiler used for hot water heat is a Keystoker dual fuel unit( rice coal/ kerosene).My question is this do I still need the L6006A that was supplied with the boiler to operate it safely when I install the Honeywell L8124A and the pair of "wet" Bulldog RB122-Elow water cut offs wired in series?

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?
