    2 good posts. Jumped to solutions too quickly without understanding lay of land, didn't I...

    How is house heated now? Why are you changing to radiant? Have you had an audit to define deficiencies and assess opportunities, or is this going from your gut?
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.
    What is comfort? Well, it AIN'T just TEMPERATURE!

    Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

    Not challenging your opinions as I am very ignorant about Hydronic. I have seen European homes used combi tankless water heater to provide hot water and warm house with radiators.

    Different tankless or just homes are smaller?

    An Old flat roofed house, built 100 years ago with 6-8" of crawl space and no heating. We used electric space heaters for bedroom and gas fireplace inserts for living area.

    relocating and putting this old house for rental. House in very high rent area, so lack of heating not a good idea.

    So force air would be difficult due to lack of accessible space. Electric is one way to go but high operating cost? Thought 1/2" water tubes would be doable.

    Just planning at this point.

    Tankless water heaters are typically designed with 35-60f incoming water temp and 110-130 outgoing. This is a fairly consistent operating parameter that is NOT the situation a boiler deals with. Boiler may deal with 120f return temp (incoming), for example.

    A wall hung boiler and a tankless water heater are not the same, although they may look the same to most homeowners.

    Electric space heating is not an approved method of heating in Calif. Heating is required by building codes. Spacepak or a Unico heat pump may work for you, or even Mitsubishi or a Fujitsu mini split system heat pump. A lot more info is needed to steer you in the right direction.

    Mini split.

    There I go again...

    Get an energy audit.
