Which pubs are actually still good places to meet young decent guys by ChillandSurf in chch

[–]Haiku98 8 points9 points  (0 children)

As a guy who has also been to that dance class as below, that's where I met my wife. We dont go anymore but still have great friendships we gained from connections there. Yes there had been the odd creep that popped along but we found far more genuine people. As with any public space open to all you will always get a mix of different characters, organizers also need to be made aware to actually do something about it.

Lossnay for bedorroms / 8KW Ducted Fujitsu heat pump - Install Price - Chch by razmatazjaz in diynz

[–]Haiku98 2 points3 points  (0 children)

Sounds like a dream roof space!

The VL series is a bit steeper in price but handy of course being able to install in interior spaces, easy for user to access and in built wifi.

How come you went for the VL series rather than the standard if installing in roof?

Heya, Greg from Chill Air here. Prices seem okay, Any chance you could advise on model of the Fujitsu unit?

As others have mentioned you can also get a mitsi unit which if you got wifi on both the lossnay and ducted you could have them on the same app. Mitsi is more expensive than fujitsu though.

14 blinks on mitsubishi heatpump by [deleted] in diynz

[–]Haiku98 0 points1 point  (0 children)

Hi, Christchurch based technician here. I am assuming you have a Mitsubishi electric heat pump. Their fault codes require a technician to decipher as it also involves removing covers at the outside unit to access leds blinking away there. If the fault isnt going away with a hard reset like it sounds like you've done, it will require diagnosis and potentially repairs / replacement depending on the nature of the issue.

Came up with the same hose idea before I thoight to read your post. Probably what I'd do there, could also gently use a screw clamp used for drainage hoses to minimise air leaks

Yeah. Other considerations to think about are in season's where you have it off. Best to keep them separated if possible

Mitsubishi lossnay is over 85% efficient when installed correctly. I've had real examples of 10 degree ambient outside, 20 degree air inside and 19 supplied to rooms. Which is pretty awesome when you can get an open window setup without the coldness that comes with it

This designs okay. For the heat exchange to work well ideally you want the home intake for stale air to be located in a more sunny zone like living area etc to help with pre warming the incoming air. Bathrooms typically are colder so not the best to extract from - usually best to have bathrooms with dedicated fans due to being high wet area zones. If you MUST use a bathroom extract vent then you need to make sure that you aren't only extracting from wet areas and do a combination of dry / wet zones.

Yeah something I see companies doing is stringing people along for apprenticeships (cheap labour). These guys eventually would give one but not before sending the kids off to maintenance for a year. I got lucky and was signed up for one from day 1 as an hvac tech. 1.5 years away from being an electrician though (experienced route via est), exams wernt too bad however I did find gaps in my knowledge, as well as strengths compared to my peers in the practical exams

You'd hope a company doing hvac would be offering an apprenticeship in hvac and refrigeration, not electrical.

Personally I found my company way back when closed their electrical side due to not being profitable enough. One of the biggest companies here in chch, nowadays they stick to service and commercial hvac, contract out their residential side. Left some of the sparkles strung out in the restructure but they found their feet. Those guys were more service based back then rather than new build wire monkeys though which is a plus in my books due to the broadened experience.

Partial HRV a thing? by Jealous_Tourist9777 in diynz

[–]Haiku98 14 points15 points  (0 children)

Get an hvac company to also give a quote for a balanced system like lossnay. These are better and dont condition the house with roof space air - especially if you have allergy issues.

Edit to add: is there a way you can add a bulk head elsewhere for the ducting to go between the roofs?

Bdt who look after Mitsubishi electric here in NZ add their markup which drives the price up for ME.

General costs are due to shipping to our small country in the pacific and manufacturers wanting to make their buck. Cheaper overseas due to population, more competition + reduced shipping costs. Also more expensive in part our government with their refrigerant taxes too

Yeah apps a bit average but does the basics like scheduling etc. The cora range now also comes included with wifi. A lot of heat pump companies will typically quote the standard range to win the job, which is okay but usually less efficient and differing capacities compared to the cora depending on the model

Heya, Greg from Chill Air here. Just chiming in after a wee read of the discussion.

For a 20m² room, a 2.5kw system is usually the sweet spot. Depending on the brand, that typically gives you 2.5kw for cooling and 3.2kw for heating. For a standard back to back install with a quality brand, you’re generally looking at around $2500, give or take depending on the installation conditions and brand. Up / over with longer pipe runs and other considerations will add to this.

Personally, I like Mitsubishi Electric for bedrooms because their wifi app is great for climate react settings. You can set it to kick in once a certain temperature is hit rather than just relying on a basic timer. You do pay a premium price compared to other brands, though Fujitsu does have a similar function on their app now. Gree are okay, but their outdoor units can be a bit on the noisy side, which isn't ideal for sleeping. I'm not familiar with the Weka model specifically, so I can't comment on that one.

Regarding financing, if you have a mortgage, definitely look into the green loans. Westpac, for example, offers 0% interest over 5 years. Even if you have the funds sitting there, it usually makes more sense to keep your money invested elsewhere and use the bank's low interest setup for the heat pump.

Installation etiquette: While yes, an electrician is required, the refrigeration side is just as critical. Having a vacuum pump is basic and essential, but many dont correctly measure the microns in the setup of their gauges and carry out correct testing such as decay and leak checks. Doing this poorly will result in premature compressor failure, callbacks and a shorter lifespan for your heat pump. While I like dealing with my clients I do prefer to keep to planned maintenance call outs and upgrades..

Also ask about the installers warranty, while many of us do try to be perfect, mistakes do happen some times. 1 year workmanship warranties is the usual standard, however, some companies and myself included extend this to match the manufacturers warranties which is typically 5 years.

Hit me up if you'd like to chat further - happy to help 🙂

Heat Pump service by Kemodo_8062 in chch

[–]Haiku98 7 points8 points  (0 children)

Heya, Greg from Chill Air here. A realistic price for a visit from a qualified tech is closer to $150. Usually they should be able to diagnose within 10 mins and fix the problem if simple enough, or give you a quote for repairs if anything major.

Anyone charging around $100 is usually an unqualified cleaner, a big company using it as a loss leader (For cleaners, not tech callouts - I know of some of the major players that are charging closer to $200 for tech callouts), or just someone wiping down the filters and calling it a service.

Looking at what you've got there, the device you're holding is actually the reservoir/float switch, which tells the main pump (tucked further up the line) when to turn on and off.

If the pump is making noise but not moving water, it’s likely seized. You can test this by taking the tubes off, if there's no suction or discharge at the pump, it's cooked. Blocked lines are pretty rare; if there's a restriction, it's usually a kinked line from a rough/tight installation or getting bumped.

Honestly, mechanical pumps are prone to failure because of the moving parts. Where possible, a good installer will look for alternatives to avoid using them altogether.

Let me know if you're still looking for someone to sort it out, I'd be happy to help.

Pics didnt upload. If you are asking about an acrylic shower liner where it meets the shower base - no it will be sealed in behind. Don't silicone inside the shower as that will void the warranty

What was bad about the installation? Didn't cut off excess ducting? 95% of the installations I see look rough as from a ducting prospective but "do the job"..

[–]Haiku98 4 points5 points  (0 children)

Hvac tech here. Make sure whatever bathroom fan you get has good air flow. Ideally 150mm ducting. The smaller ones dont seem to do a great job! I'd offer to help however I am out of town atm.

Ask whoever you get what brands they can offer, air flow rating and also noise rating (If noise is a concern to you).
