We had an ongoing problem with the existing boiler which was slowly getting worse and Paragas was recommended to us by several people. On the initial visit they offered to try and fix the boiler but there were clearly some problems so we decided that flushing out the system and replacing the boiler would give us the reliability that we need. The quote was with us and accepted within hours and the work was scheduled to take place the following week. The new boiler was installed and the gunk cleared from the pipework without any drama. John explained how to operate the new system, handed over all the paperwork and left us with a warm house and hot water. Absolute bliss! Highly recommended
