Bosch PIV995DC1E Questions & Answers

Our Electrician ran a separate circuit for our one as he said it required its own one due to the power it could put out.

Hi Alex, The supplied cable is rated for the 11kw, the cross section of the cable and the rating also depends on a bunch of other things like the length copper purity covering etc. I can't say I have measured the 3 phase (we only have single) but I did bring it up with our electrician about the single as that's 4mm2 and our run to it for 8kw (explanation below) is 5mm2. He pointed me to the calculation tables involving length, coverings, cable in air or not, inside, outside, ambient temperature etc. That detailed calc sheet confirmed that inside, flexible, 4mm2, not covered (no roof insulation), 2m long, was fine for 11kw.

In general the hob is a seriously flexible bit of kit. You can connect it single phase, 3 phase, anywhere between 2KW and 11KW. Depends on what you have available and how you want to 'de-rate' the hob. We have it connected in single phase with a 40A breaker on 5mm2 cabling and have (in the config of the hob) derated it to 8KW. This means that the hob knows it can only draw 8kw so it never blows the breaker. We have never (to date, 4 months) ever had it warn us (it does) that it has hit the 8kw limit. This is because it's practically impossible to hit 8kw, let alone 11kw. The thing boils water, stir fries or whatever, so fast that only one (max 2) of the rings are ever on boost at one time, you need all 5 rings on level 9 and 3 of them on boost to hit 11kw, it's just not a realistic scenario.

Hope you enjoy it, it's the best thing we have ever purchased for the kitchen.

You have received a typical nonsensical answer from Bosch. All care and no responsibility from the agent. The other gentleman made some relevant comments, but why purchase an 11kw 5 zone unit if it is difficult, if not impossible to get the full power on all rings. At least when we had Brandt and De Dietrich available, they were easy to wire on a dual supply, single phase circuit. Their power share relay put them generations ahead of the competitors. Maybe Bosch should restrict their sales to 2 hob units. They may then be able to answer the simpler questions that will arise. They are an unhelpful lot to deal with.

Hi there unless the cooktop is installed as per the instructions then your warranty on a crack is void. So I would suggest having your installer sign an agreement that they have installed as per the instructions. Personally I will never purchase induction again. Good luck

Why won't Bosch respond to these ones when they respond to the positive comments? Seems like a weakness in the product?

I am an electrician, we provide warranty service for many major brands. The cook top needs to be installed exactly as per the instructions. This also means that the aperture in the bench top is as per the specifications and also that there is adequate ventilation as per the specifications and instructions. This applies to any type or brand of cook top. Almost fifty percent of cook top faults are due to poor installation practices, where the installers have not read the instructions, and especially when retrofitted to existing kitchens, often the hole size is not checked or modified. The problem can be caused by the home owner going to the store or on line to buy a replacement cook top, they then either DIY it or they get someone to install it. Small surface imperfections and particularly joins in stone bench tops at the aperture will shorten the life of a ceramic cook top considerably. Poor ventilation, rodents, insects and ignored clearances will destroy the lifespan of the electronic components. Often the kitchen bench top and cabinetry requires further modification, usually expensive, which is then not done or ignored. My other suggestion is to to get Surge Protection installed in your switchboard to protect at least your cookers circuit from surges and spikes. Makes a huge difference to the lifespan of expensive electrical appliances.

Hi Darren M, thanks for your question. The appliance has a 11.1 kW total connected load.

In general the hob is a seriously flexible bit of kit. You can connect it single phase or 3 phase, anywhere between 1KW and 11KW. Depends on what you have available and how you want to 'de-rate' the hob. We have it connected in single phase with a 40A breaker on 5mm2 cabling and have (in the config of the hob) derated it to 8KW. This means that the hob knows it can only draw 8kw so it never blows the breaker. We have never (to date, 4 months) ever had it warn us (it does) that it has hit the 8kw limit. This is because it's practically impossible to hit 8kw, let alone 11kw. The thing boils water, stir fries or whatever, so fast that only one (max 2) of the rings are ever on boost at one time, you need all 5 rings on level 9 and 3 of them on boost to hit 11kw, it's just not a realistic scenario. If you select the correct settings you can even run it from a 10A mains socket, although that would be a bit silly at 2kw :)
