Thanks Tracy unfortunately that number is dead -
Does anyone have an alternative number to 07723 330860. They provide a very good service I used 2 years ago but I’ve been trying to make contact for a week but had no response. I have heard that it may have changed hands recently Roger

For the heating gurus - radiator runs
rogerc replied to TandC's topic in Boat Building & Maintenance
any system depends on the boiler and radiators being matched. a single pipe system is poor if you have 10+ radiators getting progressively cooler. but it is quite adequate for 4-6 radiators and cheaper. its a balance. -
i have a £30 heat exchanger and it heats my 65 ft boat to 28C in 3-4 hours when the outside temp is 10C a big saving on fuel cost. i also have 2 calorifiers (second hand one for £50) i only use my ex hire boat from March to end October so have only used by Alde gas boiler a couple of times in the last 10 years,

on a boat i would just use a single pipe all round the boat no need for flow and return. and the feed and expansion are usually a common pipe. your boiler will be a third or quarter of a 3 or 4 bedroom house! if you cruise a lot put in a heat exchanger for £30 to use waste engine heat and isolating valves for the heating and hot water so you can set priorities. -
i have 3x 110Ahr new domestic batteries and a smaller starter battery. i have a 295 W solar panel with a 20 A MPPT charge Controller that has a feature to turn on a load for an hour before sunrise or an hour after sunrise, (probably for lights). i lay the boat up for winter with all batteries fully charged; and the solar keeps the domestic batteries well topped up through out. but last spring the starter battery was down to 11.1V. so I'm thinking of using the load timer to top up the starter battery for an hour daily after sunset when the voltage will probably be around 12.5 V, I'll include a 10A fuse with 4m of 16A cable. will this work? and will it cause any problems/damage? some years i have permanently connected the batteries together with no problem, but if there was i would then have all batteries flat!

i have a PWM controller. does the same current from the panel flow to the battery but at a lower voltage and so lower power?

it takes so long to get my lid off that it will have run away. dead or alive.

what did you use and how long ago was it?

thanks Reg I'm not impressed with your solution that seems to only last 2 years. i black my boat every 3 years and do the water tank at the same time. and would like to do it less often particularly the water tank. i use 2 coats of Black Jack after pressure washing and its been reasonably good after 3 years, so Vatcan would be a retrograde step. does anyone have a better solution? I'm beginning to think in 3 years time a tank liner would be the solution

thanks very much for the suggestions particularly for the brackets. does anyone have any views on whether serial or parallel connection is better. also what % of the rated out put you get in winter and summer at midday and a couple of hours before sunset?

i had a 100W flexible fixed panel that got water damage after 3 years. and want to replace it. i would like a 50-100% increase in battery charge. i do a 6-8 week cruise in the summer and occasional long weekend cruises between April and October (Inclusive). initially i thought of getting a slightly larger panel with tilting mounting, but I'm beginning to think 2 fixed panels would do the same for a similar cost. i stuck my original panel which seemed good but water got under it and eventually all the paint became a soggy mess and the panel failed. I'm not keen on drilling & screwing to the roof as water might get through, so thinking of magnets. and I'm wondering about whether to have them connected serially or in parallel. parallel seems better for summer and serial for winter. and i want to avoid too many connections and keep it simple. i would welcome suggestions on the best panels and mounting systems and connections.
