Flatp plate heat exchangers

TimTim Member Posts: 37
Does anyone have comments on small flat plate heat exchangers for domestic hot water/radiant floor and solar heat transfer.

Pretty vague question, just want to get some basic comments



Thanks,

Tim

    We Use Them Regularly

    The only real issue that we normally experience is scaling when used on an open loop. In that case, we install isolation/purge valves like you would with a tankless water heater so it can be de-scaled.

    Re: flat plates

    I use them quite often for commercial dhw production. We use the GEA heat exchangers and oversize them for lower temp boiler water to keep in condensing mode. Try to size boiler temp to dhw temp as close as is feasible for this.
