Absolutely easy installation, standard connection 1/2 "can be connected with almost all pipe and hose systems, very usable insulation, very light ... But there must be something to complain about (?!): The dimensions for the mounting holes are not Would have been very helpful ... All in all, the highest possible rating!

Very high quality stainless steel storage tank with optimal insulation. Fast delivery. I would recommend to my best friend.

Good productbuild, but they could really add mounting hardware to the package.

Fast delivery good product

Everything was to my satisfaction

As expected

Except for the too small threaded connections on the boiler for engine cooling water ...

compact - well finished - efficient

Je suis très content du produit

competitive price, sharply delivery !!

After many years I had to replace the boiler and decided on the Sigmar 30L. Easy to install and connect, but the storage of warm water is insufficient. Once heated, the water is only lukewarm after 24 hours.

Now I can give a qualified opinion after I opened the boiler (with 2 heating coils) yesterday after 18 months of use to inspect the anode. As is the case with most products, this one also has some fundamental design flaws 1.) The magnesium anode is tapered towards the fastening point from the diameter to the thread (M5 or M6). Unfortunately, the thread protrudes quite far from the opposite side (base plate of the heating register). Therefore, the anode quickly wears off and then falls to the ground. I found the anode at the bottom of the boiler surrounded by Mg sludge that was formed by the anode. The new anode will not stay long in the intended place, it is to be hoped that the anode lying on the ground or the sludge that forms will also receive the protective effect. 2.) The heating coil (I use 1 for the machine, 1 for the generator) are not attached inside the boiler and swing around freely. Under the harsh conditions of a sailing yacht, the heating registers hit each other. In general, changing the anode is quite straightforward. Disconnect the cable, open the screw, pull out the heater. Of course, the O-ring should be replaced! It is also advantageous not to install the boiler horizontally, but rather at a height of approx. 20 cm on the side opposite the connections. Thus, the air bubble that forms becomes smaller and the volume of water larger. When installed horizontally, the part above the extraction pipe is filled with air that cannot escape, which is why the volume is reduced by this proportion. Personally, I would like better insulation. We are sailing in the tropics and the boiler continues to heat the already warm room. If the manufacturer chooses a different way of attaching the anode and the heating registers at least get spacers from one another, the part would be perfect. Oh yes, it would still be ideal if the connecting sleeves and any hydraulic thermostatic valve (not included) were made from the same material as the boiler is made of (stainless steel, 316?)

impossible

Vetus Boiler was better.

Good heating performance, good insulation, so that even hot shower is possible even without shore current the next morning. Because the thread of the heating element of the previously built construction and type model was oxidized after 4 years and because of the price (why a stainless steel container with thermostat / dive plunger, plastic clothing so expensive?) Only 3 out of 5 stars. Why do not you buy another product? Replacement is always easier than installing and adapting a new system.

The product I bought 2.5 years ago unfortunately only lasted 2.5 years and then suffered a short circuit - probably, as the electrician said, there was a very small water leak in the electrical installation that could not be repaired. After 2.5 years, I got nothing from SVB other than a 10% discount for the purchase of a new, exactly the same hot water boiler. Now I just hope that the second one lasts longer -(

I bought this 40l boiler and replaced it on my motor yacht with a defective one. I am dissatisfied and upset because of poor workmanship; the front cover protrudes 2cm from the body - thus the electrical system is unprotected; The 12 "pipe threads are not post-treated and razor sharp. Suspiciously light empty weight (!) - suggests a very thin stainless steel container. An exchange was not possible due to my time window! An acceptable goodwill was not offered and processed with a time delay. I have (have been) since Decades customer and have now drawn my conclusions!

Device was already badly assembled at the delivery of the manufacturer, after call at SVB the problem was quickly solved and a new one was sent.

A 10 year old boiler was replaced with it. With the old one, the water was still swarming after 48 hours. With this one, it's cold after less than 24 hours! Not usable for us because we don't drive or are online every day. He is thrown out after 2 years of suffering. Hopefully we'll find something better. If anyone has an idea, please let us know. hbinterbijoux.ch
