Recently had a twin wall flue installed on a new Morso S10-40 by a Hetas "engineer". I have been involved in the building trade for the best part of 50 years but went the Hetas route to short cut the process for a Christmas deadline. I don't think I have ever witnessed a worse bodge in all my years in the trade. I was quoted £1200 to supply 2 metres of twin wall and 1.4 metres of 6" stove pipe (we live in a bungalow). Two cowboys turned up with very little in the way of tools or equipment and proceeded to completely ignore the Morso manual which stresses the need to support the flue and NOT let the stove take the weight. At the end of the day I was left with the entire flue system swinging free on top of the stove without the benefit of a single support anywhere. The flashing where the flue penetrates the tiled roof consisted of a mangled piece of tin and several tubes of mastic to cover the bodge. I spent a day removing the whole mess, purchasing new tiles to replaced the smashed ones and installing a proper weathered flashing which, unlike the "Hetas" one, doesn't leak like a sieve. I have not paid anything to date but feel justified in paying for the (inferior) material supplied only as I have effectively had to do the job myself. I have purchased two supports to complete the install correctly.
What concerns me most if the whole Hetas cartel which is basically self regulating and therefore an open invitation for abuse by cowboys. What is the point of Document "J" if the "experts" ignore it completely and nobody checks that they are doing their job properly. It's just another of example of a bureaucratic band aid that does nothing to ensure safe, quality work. Of course, the authorities cover themselves by making a CO2 monitor mandatory - presumably to at least save the lives of the unfortunate members of the public who put their trust in a system which is fatally flawed.
