Could anyone advise whether there is a pipe frost stat on the market (not on Honeywell web site). I have lagged pipes in the loft but above loft lagging therefore could be at risk at night in very cold temps. A pipe stat coming on below 3-5 degrees would be ideal - enough to heat and circulate the water for a short while without heating the house, especially when house is unattended. Would mean a house could be left all winter with no frost fears. Would also solve the pipe work in garage problems.
