Bromleyxphil Posted November 18, 2017 Report Share Posted November 18, 2017 When we have built the boat we intend cc ing in it for a few years. Does anyone use an induction hob whilst cc ing, I know it’s all about power audits and enough battery / solar etc but I wondered if anyone was already doing it and would share their experience. cheers Phil Link to comment Share on other sites More sharing options...
mross Posted November 18, 2017 Report Share Posted November 18, 2017 Some induction hobs can be run from a 13A socket. This would mean that not all 'rings' could operate at full power simultaneously. This won't be a problem for most people, most of the time. But for a boat it would probably be better than one that draws 30 Amps plus. That would be 600 Amps plus from your 12V batteries. What sort of oven are you going for? 1 Link to comment Share on other sites More sharing options...
WotEver Posted November 18, 2017 Report Share Posted November 18, 2017 How would you power it? I’m not at all sure that an induction hob would be happy with the output of an inverter. There’s a reason 99% of boats have gas hobs. 1 Link to comment Share on other sites More sharing options...
ditchcrawler Posted November 18, 2017 Report Share Posted November 18, 2017 I think this boat has one http://nboakfield.blogspot.co.uk/ 1 Link to comment Share on other sites More sharing options...
Tuscan Posted November 18, 2017 Report Share Posted November 18, 2017 We are all electric and have an induction hob. Had we realised the power needs of the induction hob we might have made a different choice. It’s fine if we’ve had a good cruise or running the onboard silenced genie. 1 Link to comment Share on other sites More sharing options...
mross Posted November 18, 2017 Report Share Posted November 18, 2017 You have a genie? Does he live in a lamp? Link to comment Share on other sites More sharing options...
pearley Posted November 18, 2017 Report Share Posted November 18, 2017 We too have an an induction hob. It is a 2 ring CDA unit, plugs into a standard 13 amp socket and we can use both rings with no problem. It is powered via a remote start diesel generator. We also use a CDA fan oven rated at 2200 watts. 1 Link to comment Share on other sites More sharing options...
Bromleyxphil Posted November 18, 2017 Author Report Share Posted November 18, 2017 (edited) Thanks for the answers I am thinking of a 460 Ah battery bank at 24v run by the alternator and 1.5 to 2 Kw of solar I will have a back up genny as well. I was thinking of a 240v fridge freezer and wondered if one of these http://ao.com/product/si5322b-smeg-induction-hob-black-34676-39.aspx may be an “Amp too far” Edited November 18, 2017 by Bromleyxphil Link to comment Share on other sites More sharing options...
mross Posted November 18, 2017 Report Share Posted November 18, 2017 What kW will be the gennie and the inverter? Link to comment Share on other sites More sharing options...

It’s all at the planning and thinking at the moment “but the shell build starts in the next two weeks” batteries 4 of https://www.tayna.co.uk/LFD230-Varta-Professional-DC-Leisure-Battery-930230115-P3650.html. Used them before in a 24v setup and they are good. Inverter by Victron 2/3kw gennie starting with a Honda EU20i as I already own it and it’s almost new.

WotEver Posted November 18, 2017 Report Share Posted November 18, 2017 Bit of a pain starting the genny every time you want to use one ring on the hob, surely. (The EU20i wouldn’t run both rings.) 13 minutes ago, Bromleyxphil said: I am thinking of a 460 Ah battery bank at 24v 5.5kWh usable, with 12 to 24 hours to fully replace that charge. Bear that in mind. 1 Link to comment Share on other sites More sharing options...

If that is your real plan for use I would include a place for a built in diesel genny in the shell build, most are raw water cooled so mud box etc as well. You have 2 weeks to sort it 1 Link to comment Share on other sites More sharing options...
Tuscan Posted November 19, 2017 Report Share Posted November 19, 2017 Agree if you want equipment like an induction hob and funds allow plan for an inbuilt diesel generator , if you cool it via a skin tank you can also have it as an alternative source of hot water.

Bromleyxphil Posted November 19, 2017 Author Report Share Posted November 19, 2017 As always I appreciate the chance to bounce ideas around but if induction cooking requires inbuilt generation, frankly I can’t afford it. I think I will stick with gas for cooking but rely on the battery / solar for refrigeration and lighting. Please put up with my flights of fancy as the build and design is all consuming at this stage. I can’t wait to get stuck in as then the decisions have to be made rather than thought about. The 24v system solar and battery makeup are just about fixed though as it is what I am used to. Phil Link to comment Share on other sites More sharing options...

Microwave’s are prob the exception if you have a decent charging regime. Link to comment Share on other sites More sharing options...
mross Posted November 19, 2017 Report Share Posted November 19, 2017 To the OP. It's very pleasing that you are receptive to advice. so many ask for advice and then object when it is not what they wanted to hear! So, please, keep the questions coming, there is hundreds of years' worth of experience on this forum. 2 Link to comment Share on other sites More sharing options...

Also there is a very good reason that 99 percent of boats cook using gas, well several very good reasons such as. Cheap installation costs. Cheap to run. Very controllable. Very very safe. Very low maintainance. Link to comment Share on other sites More sharing options...
