UK engine block heater

yes i did....i'm in ireland but i got it post from
toyota
pentagon sheffield

part no is tpz434-g0790-3z del to me was about 113 uk pounds

any more info needed let me know!

 

well this one is genuine toyota part...and 240v to suit our voltage

works great i have it on everyday 21/2 hrs before i go work ......

 

As an alternative, look at the DEFA pre-warming solution from Norway.
Here's my journey to get one and fit it myself. In the end, it was fairly easy, but as you can see I had to make a few discoveries first. There's no DEFA fitting agents in Australia... Waeco are associated with car fridges and refrigerated seat covers in Australia!

IMHO the DEFA is much better integrated and "resolved". The water-proof fittings, the ability to add a cabin heater and battery charger make it worth the extra.
When I was looking for an EBH last year, there was no 240 volt version of the "Canadian" EBH. I stumbled across DEFA and was sold.

nice write up on installation........but there is a 240v available and part no quoted above

i route mine down behind number plate thru the foam ...so it is hidden and facing down looks part of car

[the black on the grill is just grill blocker]

 

Hi Edwardob
So you run the cable from the EBH under the engine? Where do you earth it? I toyed with that idea, but decided that the negative terminal was the right place to connect and there was enough clearance without drive belts in the way. And since the socket will only feed in from the outside, you've got to get the routing decided. Fortunately, my long arms will reach over the back of the engine, so I could unplug the cable from the EBH and try another route.

The DEFA technical notice provided to its installers (and provided to me by Bjørn) has the plug on the lower grill on the right (left, if viewed from the front). Not only does this interfere with lower grill blocking, it takes the cable too close to A/C tubes in the cramped space on the right (left if viewed from the front) entering the condenser for my liking.
If the visitors to my blog from Norway, Sweden and Finland are anything to go by, the instructions "keep cable away from A/C and brake lines" aren't adequate for the DIY installer. Google "defa ebh install prius" and you'll find my blog. The responsibility weights hard.

no over the engine...well between the engine and big electric thing...kinda goes down the middle.....then pushed tru foam above radiator[little ap] and the wriggle it tru bumper foam

 

Eek! It ends up as a nice stealth install, but I can't imagine how much skin it required.
When I was on my back staring at the rear of the engine and wishing to avoid the A/C lines on the right, I couldn't find a safe route to avoid the exhaust manifold on the left. Without a bracket I wasn't sure that the cable would stay away from it.
I considered the left (looking from the rear) is an easy path to the lower grill as there's a nice opening covered by foam with nothing else running through it. But I couldn't find a safe way from there. That's the best path for the Canadian EBH because it is near the top of the block, but not a model for the DEFA install, if you ask me.

Are DEFA EBH common in Ireland?

 

skin graft from my rear end did the trick!

ebh common in ireland??? not really ..probably because it not considered cold enough

but i really appreciate it all year round because the engine is already warmed up..and saves about 50 cent per day fuel
bout 10-15 euro per month1

 

There are definitely two schools of thought on Engine Block heaters. We're in a very temperate, coastal zone, but use ours year 'round. And get some puzzled looks from traditionalists.

The part here was around $90, and installed $300~400. I suppose I could have done it myself, but got it at time of purchase, and with the big numbers flying around (and not feeling like crawling under the car and doing battle right away) thought what the heck. Don't expect it to fully warm the engine: like any block heater, it'll raise the coolant temperature about 20 degrees centigrade. Basically gives the engine a leg-up in the warm up process.

 

Using all year round is not so silly.
The DEFA support and download page has a number of good documents including the Technical Handbook; the first few pages of which show the difference between cold and warm starting for fuel consumption, emissions and engine wear according to their tests.
In my experience, the DEFA EBH can take the coolant from 5°c to 45°c in 2-3 hours. This is in a garage with ambient temperature of 5°C even when it is below zero outside.
Upon startup I will using move from the garage on EV only but will try to trigger the engine to run. As the coolant circulates it first gets colder as it hits the radiator and then quickly gets warmer, reaching 55-60°c in about 2 minutes of gentle driving. So you still need to run the engine, but you get to higher stages and therefore more efficient running sooner. And the heater works.

On average Canberra has 60 nights per year below 0°c and 92 per year below 2°c. In fact, the last 2 nights have been 3.7 and 4.1°c and its only Autumn. Since 10°c is a cold start, there's plenty of days that I'll use the EBH and grill block.
