Outfitting your bathroom under the bath, he decided to make a strong (about 3 — 3.5kW) and reliable heater. The most appropriate seemed to be elektrokemisk in a tin bucket with asbestos cement terminal block and brass studs, the closed hinged metal housing (Fig. 1). But when I placed this heater in the socket, felt the smell of burning.
The culprit turned out to be badly spring-loaded contact, and loose terminals. After the elastic cheeks in the contact socket has been properly pressed by pliers, and the ends of the wires in each terminal clamp thoroughly stripped, twisted, soldered and securely tightened screw, socket almost stopped to bask, although the power connected to it, the load was 3.5kW.
The next problem is to find the optimal design of the heating element to kamelek. Began to experiment.
First tried monobrow burner 1.5 kW, produced by the domestic industry for household electric stoves. Established in kamelek in a single copy, it could (15 hours!) warm bath-the bathroom only to 50°C. are Then applied popular among the homebrew the combination of two superposed plates connected in parallel (Fig. 2). And I realized: this heater is not for me. First, because of the margin of safety in the dual burners only enough for 3 — 5 sessions. Secondly, the production of combinations takes a lot of time and effort. After all, the staff terminal block has to be remove, as the metal disks on which they are mounted. But in the standard “flange” of each of the plates is to cut a recess for the conclusions. Besides expensive work the heater, some burners are worth! And thirdly.
