I have been quoted £16000.00. This is much more than a traditional heating system. We are also looking at the air source pump. We have been told that the gound source heat pump is the most efficient but are also looking into the air source option coupled with air exchange. Can you enlighten me further. Would be interested in other comments which may be helpful.</p> <p>Barney </p>
