I purchased a Sanden Heat Pump hot water system from Laros. I did not know much about heat pumps so needed a lot of advice. I cannot speak highly enough of all the staff who helped me through the entire process - from the initial enquiry right through to the installation. Everything went so smoothly. I used one of their recommended plumbers (Tim O'Shea) who did excellent work and tidied up afterwards. The Sanden has now been installed for nearly 6 weeks and we are very happy with our choice. The heat pump is installed immediately under the bathroom window (always closed), and when it is operating we can be in the bathroom and not even hear it. From my experience, I can definitely recommend Laros Technologies.

I really have valued your entire team's input into not just the windows but all aspects of the build project to passivhaus, but the quality of the products you offer speaks for themselves.

There isn't a huge difference in price between high quality Australian, German or British double glazing products and the triple glazing offered by your company.

The problem was: because of the steel's temperature conductivity, there was a potential for mould problems caused by condensation, which would have rose up the wall. But it’s all taken care of now thanks to LAROS and Pro Clima: they sell truly environmentally-friendly and people-friendly products made for the New Zealand climate.

Want an energy efficient house? When we finally found a builder prepared to tackle an ICF build, he sent us along to LAROS – and that changed our world! Andreas took 20 minutes out of his busy schedule to sit us down and tell us about ‘Passivhaus’ design – we never looked back. R6 insulation at roof level wrapped in a gortex shell, taped down to make it airtight and big, beautiful, TRIPLE glazed windows and triple sealed doors from Germany. The heat exchange ventilation systems keeps us warm in winter and keeps the heat out in summer. The SANDEN heat exchange hot water system and the 5KVA Solar system means power (and gas) bills are a thing of the past. We love our comfortable, economical, quiet (seriously) house. If you’re thinking brick veneer don’t sign until you’ve heard about Passivhaus.

We’ve been in the house for 2 months now, and through warm sunny days, gloomy days and overnight temperatures of -6 oC, the house has really shown that it is delivering on the promise. The temperature has not dropped below 19.2 oC (even with the freezing nights) and has stabilised at a comfortable 21-23 oC during gloomy days and cool nights. The higher temperatures, due to the solar gain on sunny days, are easily managed through opening the clerestory windows in the living room and tilting other windows throughout the house to manage a very comfortable temperature.

I purchased the SANDEN hot water system last year and am very happy with the results.

In my opinion, Dopfner windows are the best on the market. Having installed the Dopfner windows at John's and seeing the finish, as well as the quality, I can't fault them.

We would highly recommend Laros and Dopfner. The Laros team really know their product. Our consultant understood our needs very well and saw the project through from the initial quote to retrofit all our windows and doors to the end of the installation. We live near a busy road and the triple glazing means we no longer hear any traffic noise. The design of the windows lets in more light, we use less gas heating and the look of our home is more modern. Our consultant also worked closely with our builder who did a superb job on the installation, with top-notch finishes inside and out.

Hello, we recently purchase two Lunos heat exchangers from you. The difference in air quality in our upstairs area after installing them is amazing. It has gone from very bad to fantastic. They are quiet enough that we can leave them operating over night on the lowest setting, which is great for fresh air all night. The higher settings are noisier but useful for a quick purge of old air for new. Thanks very much.
