Good Evening All,

That's me hobbling about having bruised my knee exiting the kayak this afternoon. Battery recovery continues with the latest figures below. Battery 12 will get one more day to show signs of recovery before being taken out and replaced.

There is no immediate prospect of a great deal of sunny weather so I think I'll end up implementing my Economy 7 charging for now just to 'test' the system.



Too much opposition from cheap Chinese competition means I no longer sell our desulphators.

I think I may have secured a genuine Growatt 5kWhr lithium battery having gone to effort of recovering the Trojan's.........

Regards

Richard

Good Evening All,

Well a couple of pictures showing 8off Trojan's now connected to the Growatt:-



The next shows the batteries connected to the Growatt, it is all very much work in progress:-



As I understand the G59 application it requires the addition of a G83/2 capable inverter as a minimum. Given I only want to add around 1650W of panels what inverter would suit?Huh An SMA SB1700 is only G83/1 as far as I can tell.

Regards

You're adding 1650kW of panels, I don't think there is anyway a SB1700 will allow you to get the most of of all those.  Grin

Good Evening All,

Growatt and PV expansion is on bit of a back burner currently.

The focus has gone back to the refurbishment of the Dining Room - part of the 'big' project to make the whole house more energy efficient

Once the floor had gone off sufficiently the joiners have been in and erected most of the framing except in to the window recess until the new window is installed.

Prior to them arriving I stuffed the upstairs floor joists with 200mm of fibreglass held in place with netting.

I'm now on with installing the rigid insulation -



The plumbers have now been back to install the Mira Adept Eco BIV shower along with modifying the water supply to provide pressurised hot as well as cold water  -



Nothing too exciting there you might think? Well it replaces a Mira Elite Mk 2 which was a 9.8kW unit so we're now using hot water derived from either solar PV, solar ET or the GSHP.

Mind I do now have to 'repair' the plasterboard wall in my younger son's bedroom -



Regards

Richard

That wall looks great!
Hoping to do the same soon, was that any particular foil tape or just ordinary foil tape as used in ducting installs?

TT,

I just use 'normal' aluminium foil tape. Installing the large pieces of insulation is pretty quick but the smaller bits and the taping is very time consuming................

I'm just about ready to start the 25mm overlay part today.............

Window installers due today (yes a Saturday) as they overran on another job on Thursday. The joiners will then be back in on Monday to complete the framing around the window and complete the insulation install. Hopefully a start will be made on plasterboarding whilst I'm away on a course next week.

Regards

Good Morning All,

Due to pressures elsewhere I haven't been able to make any progress on the Growatt front. The Dining Room is progressing though and has now been plastered. We're still trying to sort out replacing the original plaster mouldings or a very similar pattern.

The plumbers were back this weekend to take out the circulating pump for the UFH and fit a bypass/ bleed arrangement (using a Zilmat/ Inta automatic bypass valve). This allowed me to fit a TRV to the Hall radiator which will hopefully allow the heat pump system to run at an overall lower temperature than last 'winter'.

Despite isolating all radiators I still ended up draining the system and had to pour a whole lot of liquid back in through an upstairs radiator and we're still trying to get rid of air in the system on both the heating and DHW circuit.

Hopefully the heat pump heating circulating pump will have enough 'grunt' to circulate water around the whole system.

I have installed Danfoss RM24 thermostat's in the kitchen and Dining Room wired back to a Danfoss FH-WC 24V controller as it was stuff I had in a box from when the kitchen UFH was installed.

I'll post pictures later once I've found the lead to download the pictures............

Regards

do you not have a separate pump on the ufh? i have 3 eco modulating pumps, one on ufh one on wood back boiler and one on the new heat pump.
have i gone over the top pump wise?
dont plan to use heat pump in winter as wood does all our cold needs.

Good Morning All (again),

Pictures as promised, firstly overview of UFH manifold although nothing special:-



The most recent change i.e. fitting of bleed valve and re-fitting of isolation valve:-



and, finally, the heating wiring 'centre':-



Now back to trying to vent all the air out of the system..........

Steve - time will tell whether we need to put a pump back in but it would need to be 'modulating' so as to not 'steal' all the flow from the rest of the system as its predecessor did.

Regards

Richard

Good Evening All,

Well the latest 'toy' turned up today. It was what three years ago now that I noted the 'howling gale' coming back through the Elica extractor hood in the kitchen. Clearly the conventional pivoted flap on the outside wall wasn't terribly effective so I started looking for an improvement.

After some internet searching I ordered a Helios vent flap which uses a mains powered bimetallic strip as far as I can tell and has proved to be utterly useless in that it won't allow the extractor to be used at anymore than the 1st setting and doesn't always close effectively.

Aided by my wife I ended up buying a 'professional' vent flap and actuator which now needs fitting and will have to wait until my next leave as some kind of 'hood' or 'enclosure' will need to be sourced. As far as I can tell there is no ready provision of 'total' isolation readily available on such as cooker hoods.

We also have a 150mm extractor in the Shower Room with a conventional non-return flap which isn't overly effective and irritates our youngest son no end and will also be fitting another extractor on the bathroom in due course.

This is what the actuator and vent flap look like:-





It may seem over the top but I don't see what other solutions there are?

Regards

Richard

We had a sprung flap non-return valve in the pipework for our bathroom extractor fan in the last place which worked really well - didn't open until there was a significant positive pressure, and pretty well sealed with something like silicone rubber around the outside of the flaps. It'll be a problem with kitchen extractor fans, however, due to the grease in the air which will probably force the seal slightly open.

pdf27,

We used to have a simple 'hair' spring loaded type previously and it used to 'oscillate' as well.

I find it strange that in these days of increasingly tight building regulations that there aren't more 'engineered' solutions to the ventilation systems we're now required to install.

How do you install a cat flap in a Passivehaus?Huh

I finally got around to replacing the filter element in our water pumping 'plant', what a horrid brown colour it was. The picture below shows my set-up before I box it up again. The unit hanging off the baling twine is a heater - I need to install this a little more professionally but as the baling twine does the job..........



Still venting air from the system but at least we managed to get three showers and a bath out of the system yesterday evening!

Having managed to get some radiators bled of air and the TRV's wound down to the required settings we did get flow in both UFH circuits so we'll see how it goes as autumn sets in although given a temperature of -1.7oC was reported somewhere in Scotland overnight maybe sooner?

Regards

Richard

i have autovents on all my rads and floor and at high points, we did have issues with air but no more, especially since the new water pumps, which dont suck air in on the open vented side, but still pump up 3 floors high.
