A very compact hot water boiler. It heats up very quickly; it takes about 20 minutes on shore power, or 30 minutes with the engine running. All the connections on the front are also good. We replaced the boiler after 20 years because it started to leak around the casing. In our opinion, it has a good lifespan.

Technical question

How long does it take to heat the water when using the engine (or diesel heater) as a heat source?

Answer from SVB customer service
Sven W. | Dec 14, 2023
User image of Sven W.

Hello Szymon, that has some factors, like: engine size, Boiler size, flow rate of the number of revolutions per minute. A short tour of maybe one hour should be enough, otherwise there is a electric heating element to make the rest. Yours SVB-team.

General question

What is the warranty period for the B3 water heater

Answer from SVB customer service
Sven W. | Mar 6, 2023
User image of Sven W.

Dear Sheila Ann, the manufacturer gives a guarantee, but without specifying how long or for what. Unfortunately, as a retailer, we cannot provide any more precise information, only the manufacturer can do this. Yours SVB-team.

Technical question
ATHANASIOS M. | Jan 20, 2023 Flag of English

Kindly advise me if this is 110V or 220V. I want to order the 30L 1200W. Thank you in advance.

Answer from SVB customer service
Sven W. | Feb 1, 2023
User image of Sven W.

Dear Athanasios, if you order this Boiler, you will get this with a 230 Volt, because we only got 230 Volt in our stock.. Boiler with 110 Volt, we have to order from the manufacturer. Your SVB-team.

Can anyone advise on what plumbing parts we need to plumb the water heater in.?

Answer
Hugh G. | Jun 1, 2020

You'll need to make the connections to your water system and your engine. The ports are all half inch male threads so you will need four female fittings. The type of fitting depends on your water system hoses and engine hoses and the diameter of each. I used 15mm half inch hose tails with jubilee clips to connect to the engine cooling system and standard half inch flexi-hoses to connect to the copper water system pipes via compression fittings.
