Insufficient Domestic Hot Water with a Domestic Hot Water Coil

When you have an oil fired or gas fired boiler with a built in tankless coil, that's getting very little domestic hot water.

Check the aquastat settings, should be 180 degrees low setting - 200 degrees high setting

The most likely issue is the coil being clogged with sediments. The only real way to restore the flow of hot water is to replace the domestic hot water coil and be sure to replace any temperature mixing valve at the same time.

If the above check list do not solve your problem, call our service department at 215-945-4833 right away for service. Be sure to have your equipment model number  and age of equipment.
