Anyone familiar with 1" electric hot water heating element hardware?
I have a couple of 2" threaded holes (for heating elements) in my boiler.
The holes are labeled as 2" on the diagram. I found a picture of an HS Tarm (larger size than mine) where they screwed in some kind of copper fittings, it looks like some kind of heat exchanger. (Just to the right of the oil burner). This one has three holes, whereas mine only has two. Mine has 2 screw in plugs. But, the plugs appear to be about 2.4" across! The plugs are marked "SAV 2", whatever that means. (Made in Denmark). I found this fitting, Model 311 B-2112 Buy the LDR Industries 311 B-21 2x1 Galv Bushing at Hardware World - The world's #1 home hardware site And, this heater.. Trailer Parts Superstore - Screw-In Water Heater Element (1000W-120V) #02103 The scheme is to connect 115vdc from my 800w PV array to this 1kw heating element.. So, I'm wondering if this is a pipe dream or maybe possible.?. Will this bushing allow me to install the element in my boiler? (If the 2" bushing fits into the 2.4" hole correctly).. Or, does the element have a different type thread? |

At Nominal Pipe Size - Wikipedia, the free encyclopedia
I found out that 2" NPS has an OD of 2.375".. No wonder they pay plumbers so much.. |

Too bad you don't have a small machine lathe, you could make such an adapter.

I actually do have a small lathe (Chinese), but my skill at cutting threads isn't that good.
From what I've been able to glean, that Model 311 B-2112 bushing should work.. If not, I have a machinist buddy who can make the part for me. (Using a much better lathe). |
