Just this week finished installing a 4 outlet system on my boat. Got it at a good price fron the SBS. Very straight forward installation. Two electrical conections (all terminals supplied) plug and play I guess? The hardest bit was plucking up enough courage to drill a 50mm hole through the hull of my new boat which hadn't hit the water yet!! works brilliant. 10 mins the hole boat (incl cockpit) is warmed up. Don't know about spares but a service costs 70% less than the market leader (IMHO). Quiet running etc. 1 forgot some bits and I picked them up from the distributors at Milbrook same day, no charge!! Service indeed.

How much (roughly) is a heater I've got a Sealine S37 with all the ducting already installed what needs to be done. Diesel connection I guess and some electrics..is that it??
