Review: Exactly what I needed! - Having a mixture of old and new radiators, and being unable to find a plumber willing to undertake an upgrade of the old radiator connectors because two of the old thermostats had failed, I fitted these adaptors and bought new thermostats to go on top. Easy to fit and does the job until I can finally get a plumber to sort it all out properly. Thx. Review: Retrofitted Legacy Heating System - I needed this to retrofit a legacy heating system to work in conjunction with my nest thermostat. It did just the job. A simple piece of hardware that can bring even an old radiator system up to standard. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Myson | | Part Number | 2TRVADAP | | Product Dimensions | 3.2 x 3.2 x 2.8 cm; 20 g | | Manufacturer reference | 2TRVADAP | | Item Package Quantity | 1 | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 20 g | ## Images ![Myson Adaptor for TRV 2-Way Thermostatic Radiator Valve Head 28mm to 30 mm adapter - Image 1](https://m.media-amazon.com/images/I/81OcBXuj7rL.jpg) ![Myson Adaptor for TRV 2-Way Thermostatic Radiator Valve Head 28mm to 30 mm adapter - Image 2](https://m.media-amazon.com/images/I/81kcEMH3hNL.jpg) ![Myson Adaptor for TRV 2-Way Thermostatic Radiator Valve Head 28mm to 30 mm adapter - Image 3](https://m.media-amazon.com/images/I/81TdKdGdneL.jpg) ![Myson Adaptor for TRV 2-Way Thermostatic Radiator Valve Head 28mm to 30 mm adapter - Image 4](https://m.media-amazon.com/images/I/814qMJXpEyL.jpg) ## Questions & Answers **Q: Hi.. the thread on my old valve body is m28 x 1 male and i need to get to m30 x 1.5.. that's what this adaptor is made for yes?** A: I also had M28 x 1.0 on my valve. I had to get this from Amazon Germany though and it fitted perfect. This is it https://www.amazon.de/gp/product/B077G99CFD/ref=ox_sc_act_title_1?smid=A3JWKAKR8XB7XF&psc=1 **Q: Ad3 adapter to adapt an m30x1.5 thermostat to the m28x1.0 valve.is this the dimension of this product to adapt drayton trv3 to tado smart head** A: No this will not fit the TRV3 we have, i believe is m28x1.0. **Q: Will this adapt old Drayton valves to tado valves** A: I bought these for the exact same purpose... but they didn’t work for me. I think it really depends on the exact size of your existing valve. I ended up having my Plumber change out the valves for ones which the Tado TRVs fit directly. **Q: Has anybody tried to use this to convert a drayton trv3 to use a hive head unit? some comments say it works with a trv3 and others say it doesn’t.** A: Sorry no idea it just converts the 28mm thread for the standard TRV to 30mm for the new standard heads. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what I needed! *by T***R on 18 December 2022* Having a mixture of old and new radiators, and being unable to find a plumber willing to undertake an upgrade of the old radiator connectors because two of the old thermostats had failed, I fitted these adaptors and bought new thermostats to go on top.
