    Most solar controllers have several functions and are widely available in the UK. One being cylinder loading via solid fuel.
    The STDC which is available in 4 versions is about a £100 quid. Three PT1000 sensor inputs and PWM 0-10v relay for speed control of high efficiency pumps.

    Navitron sell the STDC range of controllers.

    Theres almost 40 models in total. The most expensive being around £400 for multiple cylinders and other functions.

    Keep in mind if your pellet boiler is sized accordingly you can use standard 240v stats with phials and latching relays and the buffer will charge fully from a space heating demand even if the demand ceases in a few minutes.
    It just means the buffer is only fully charged automatically within the allocated times of your heating programmer schedule.
    Not running 24/7 losing heat for a past time.
