We had five Fischer heaters installed recently; three to replace old-style night storage heaters and two others to deal with cold spots. They are certainly expensive but they do exactly what the specifications claim so we are very pleased with the result. To early to comment on average energy usage but the accurate timed thermostats give a good degree of control. Only one distraction really - early on we fielded a few specific questions over the phone and Fischer Heat struggled to answer them, referring us to Fischer Energy, who ......... referred us to Fischer Heat. So, a few communication problems for a while but all resolved in the end.
