Sure, any heat source can be used for hydronic radiant.

Be aware that snowmelt takes a lot of boiler capacity. The boiler you have may not have the capacity to heat and melt snow.

It may be wise to have a dedicated boiler for the SIM (snow ice melt)

Of course you can do radiant with oil. Your heating water the fuel does not matter. You can heat water wit electric, natural gas, propane oil or solar.

You just need an installer who knows how to do it and you need the right equipment pump, mixing valve and the know how to pipe it right.

So, here's the situation - I live out in (semi) rural PA. Needless to say, no gas in the street. My (new to me) house has oil - a Crown, about 15 years or so old. Currently, the heat is via hot water baseboard. Boiler control is a Resideo electronic, flamethrower is a Becket of some sort. Nothing fancy. Two zones. Domestic water was a coil, but now is a heat pump hot water heater. Propane exists for the stove.

The front walkway is being done, and snow melt piping will be put in fr future snow melt implementation.

But that got me thinking - can I do radiant heat in the house with an oil system? The boiler still has life, but I've not heard of anyone doing radiant (or snowmelt) with oil. Radiant has a few advantages for me - my kitchen has basically no room for radiators, and most of the other rooms fall short, too. The house sits over a concrete floor basement, so installation access is ideal.

Anyone ever seen radiant/snowmelt with oil? I know radiant is lower temperature, which seems to be something a conventional oil boiler may not like, and I've never heard of a modulating condensing oil boiler. Should I look into going propane next summer? Would hate to ditch a boiler with life in it (and it's in good shape, too)

Thanks!
