Home heating based on Webasto.
TL;DR
- A small-apartment heater uses a Webasto Thermo Top Z/C/D from a Rover 75, a Nissan Almera radiator, and a separate diesel fuel pump.
- A PlayStation 3 power supply replaced repeated DIY supply attempts, and a PWM controller keeps the radiator fans from blasting at full speed.
- The Webasto cuts off below 10.5V, while a temperature sensor in the T-connector turns the fan relay on only after 40*C.
- Parts cost about PLN90 for the heater, PLN5 for the radiator, PLN60 for the pump, and weekly diesel use is about 5-6 liters.
- The system heats quietly, vents exhaust outside, hides under a small worktop, and later may add external combustion air and SMS remote start.

Hello. Some time ago, I rented a small apartment. It had one major problem - heating. Electric or gas heaters were out of the question.
After much searching, I found webasto on eBay. It comes from the Rover 75 car and is powered by diesel fuel.
A dedicated fuel pump works with the webast, and the heat exchanger is a radiator from Nissan Almera.
An interesting element is the power supply. After many attempts to create a suitable power supply (the Webasto turns off when the voltage drops to 10.5V), the choice fell on the PlayStation3 power supply. It works great in its new application. To prevent the radiator fans from running at full speed all the time, a simple PWM controller was installed. Thanks to this, I can smoothly adjust the speed. The heating is quite quiet, exhaust gases escape outside, and the fuel tank is located in another room. A small worktop is usually mounted above the entire heating system, so it is practically invisible.
The stove itself also controls the radiator fans. The activation signal goes to the temperature sensor mounted in the T-connector at the Webast output. It turns on only after reaching 40*C. It, in turn, turns on the relay in the power supply and supplies current to the PWM controller that controls the fans. A very clever solution, the heating blows warm air, not cold.
Prices:
Webasto Thermo Top Z/C/D - PLN90
Nissan Almera radiator - PLN5
Fuel pump - PLN60
Power supply - PLN7
Thermostat - PLN5
Hoses, cables, parts for the regulator, relays, clamps, etc. - PLN15
The average fuel consumption, when heating 3-4 hours a day, is about 5-6 liters of diesel fuel per week. Average PLN7-8 :D
The only plans are to make an external intake of air for combustion, and remote starting via SMS, but that will happen in the future :)

Webasto consumes the most electricity when heating a candle, but this process burned my ATX power supply :D Is the control of the Webasto itself based on the original controller or is it solved in some... [Read more]
I know the opinion about us abroad, mainly that we do everything well, quickly and thoroughly. And we like to drink. I was counting on constructive criticism, not complaints that it`s ugly. But I will... [Read more]
How many rooms do you heat with it? Do I understand that only 1 room; ) I`m mainly concerned about the square footage what temperatures outside? Have you compared which will be cheaper in fuel: gas,... [Read more]
1 room, kitchen and bathroom. The entire apartment measures approx. 40 m2 in total. from -5 to 12, as in the UK in winter. Initially, I wanted to buy an ordinary boiler, but I can t like gas, and... [Read more]
You can`t see it in the photos, but I would also install an expansion tank and maybe think about replacing the water with coolant. Coming back to the fact that a Pole is capable, others are simply jealous... [Read more]
My friend carot Can you estimate the fuel consumption of such a heating set? [Read more]
Cool DIY :) I have a question, where do you discharge the exhaust gases and how noisy is the whole thing? With and without air supply? [Read more]
I decided on a radiator from Almera because it has a built-in reservoir and the system is filled with water with antifreeze added. 0.3-0.4 liters per hour of operation. [Read more]
It`s probably not that cheap after all. Taking into account the price of diesel fuel in Poland, the average is about PLN 5.5/l per hour PLN 1.65 - 2.2 / hour of work At the price of electricity around... [Read more]
Yes, you are right, but there is one basic mistake. Here, oil costs 1.39 per liter. I`d prefer electric too, but oh well. People on barges here, even though they have free electricity, also have webast... [Read more]
If you have a marine nearby, check if they have red diesel, in my area it`s 1f each, so it would be even cheaper. [Read more]
I just don m looking for red, but everywhere you have to order at least 500 liters. [Read more]
1.39 is the price for red diesel, I understand? Is it any different from heating oil? As far as I know, red diesel can be refueled in tractors and refrigerated trucks. The car will also drive smoothly,... [Read more]
In Poland, you buy a liquefied gas cylinder and a suitable ceramic heater. A bit damp, but at least it t smell like oil. [Read more]
If you have already decided to heat with diesel oil, you have not thought about using a forced-air heater - less electricity and oil consumption, much quieter operation and fewer toys around [Read more]
No, for regular diesel fuel. This is what humidity is all about. And no, it doesn`t smell like oil. I thought, but the prices of blown and water ones differ significantly. [Read more]
yes, and this is an argument, I once had the same problem as you, I installed a storage furnace, but the current was mmmm. There are no cheap solutions in winter, although I saw a kerosene stove, but the... [Read more]
For me, heating makes no sense. It would be better to use natural gas heating if you have access to it. [Read more]
If I had access to natural gas, don t have access to it, we only have propane from a cylinder, and anyway, oil is safer :) [Read more]
