I was not thinking of someone using an Altherma hot water heat pump and gas hot water in the same house as that would be a duplication. You are right about many hot water heat pump models being inefficient but the Altherma is a high end unit with a heating COP better than air to air heat pumps in the same kW range. When Daikin upgrades it to R32 it should become more efficient.

 

 



Planitherm is not a single product but a brand collection of low e glasses. Visible light, solar gain and heat retention specifications differ between different Planitherm low e products. Finding out which Planitherm variations are available in New Zealand and what their specifications are would be useful. Specific low e products should be chosen and specified or else the glazer could install anything with the Planitherm name on it.
Overseas it's possible to combine the low e glass with a higher grade of clear glass but that would cost more if it is available.

 

 



I've seen this multi purpose cool drawer product and thought it looked really useful

It's very expensive in retail but may be much cheaper through the builder.

 

 



I suggest changing the gas cooktop to this flushmount model

It won't have pots precariously sitting up in the air like their gas on glass models. If the price is unreasonable you could get the very similar Smeg model.

Why not get rid of the rangehood, and have an integrated one in the cupboards above the cooktop. It can save some space, and visually looks better / more modern, as you don't have a break in the overhead cupboards.

Are the integrated rangehood just as powerful as dedicated/outside located one's? I have been told that NZ law states minimum 750mm clearance from cooktop to rangehood which would mean with integrated that side cabinetry will also start from 750mm space difference between cooktop island and bottom of cabinetry making reach for taking things out of cabinetry difficult?




Do whatever you want to do man.

 A kitchen designer should be able to get the sizings working right. Not too sure on the power, but they should be effective enough, and different manufacturers have different ones with different power. It does possibly depend how tall the users are, as to how comfortable the cupboards are to use.

That rule is in the gas codes for clearances to a rangehood. Don't know if there is a different measurement in the electrical codes for clearance above an electric cooktop. Also the clearance is higher again if your cooktop contains [or is] an indoor BBQ, lava rock grill ect. Due to fat flareups.

Still working on the final kitchen design but decided to go with only drawers instead of cabinets underneath the benchtop after @k1w1k1d suggestion in an earlier post. This will provide with more room, better ergonomics and finding things quicker.

Has anyone heard anything about SmartVent Synergy Plus system? I inquired about it and received the below house plan and documentation about the product. They have a 5kW and 7kW system. They have recommended a 5kW system for upstairs (they say it's actually an overkill for the first floor) and 7kW for downstairs. There is no outside unit for this system. I know the SIMX ducting is really good quality stuff they use for SmartVent. Idea is that the heatpump function kicks in when desired temperature is required that is set on the controller. It only needs to heat or cool the air that will be the difference between air temperature outside as it used that when it enters our leaves the house. Basically an ERV + Heatpump solution without an external unit. Any thoughts?

5kW was roughly quoted around $12K and 7kW was $14K for SmartVent. I have not had a proper quote come through yet for Lossnay because all Mitsubishi agents in Hamilton are useless with ducted solution specially trying to incorporate a lossnay unit with their heat pump units. They all keep pushing for mini splits/Hi Wall units. The Mitsubishi solution for it's heat pump integration would require 400 ~ 500mm wide ducting where as SmartVent tops at 200mm. I think the designers for Mitsubishi are worried about not enough space in midfloor cavity and ceiling roof space even though I have got them more than the required space.

It says on their website

 

"Energy Recovery Cores

 


 

A choice of both new generation EV paper cores/polymer cores best suited for your home."

 

 



Paper ERV means the heat exchange core is permeable and humidity is transferred between the incoming and outgoing air stream. That's good in some situations like in very cold climates where low humidity is a problem but humidity retention is not a behaviour we want from a ventilation system. The Lossnay is a permeable system.

but if combined with a heatpump the permeability of the material shouldn't be to much of an issue, because humidity is much more noticeable in the summer when the heatpump is on cool, which helps removed humidity anyways

Received the updated kitchen designs today. Under bench storage changed to drawers and both microwave and oven has been moved to the scullery. I don't like the fact that scullery bench top space is really empty. I will ask them to place over head cupboards like kitchen cooktop Island's at 700mm height start. It's looking a lot better now.

Looks good. I would have some more of the shallower drawers. as deep draws aren't that usable. My shallow drawers are used more than the deep ones. Also I would make sure to have power sockets in the island. Just been to one house that didn't have any so no way to put in a laptop when sitting at the island
