Can a hydrotherm tankless coil be replaced without replacing the boiler?
Yes. The coil bolts into the boiler through a coil plate. It can be removed and replaced with a new coil and gasket.
Should the coil gasket be replaced when fitting a new hydrotherm coil?
Yes. Fit a new gasket every time the coil is removed, because the old gasket will have compressed and may leak.
How do I identify the right hydrotherm coil?
Confirm the boiler series from the rating plate, then match the coil plate size and bolt hole count. For example, the Aquarius coil has a 7-1/2" diameter plate with 6 bolt holes.
