Product page enhancements

[ihs1]

HI

ive been on shopify over 6 months now and at the beginning i did everything myself including design and layout - as i needed the site up and running. 

im now looking back and im not getting high conversions and the design doesnt look appealing

can i have some feedback and advice on what i can do to enhance the product pages. see link below to one of my products:

https://infraredheatingsupplies.com/products/super-efficient-ceiling-mounted-panel-595x595mm-400w

i have some accordion tabs on the right with metafields info

there is also a lot of text under the description

around the add to cart there is also some key features and some icon showing my stores credibility

please can you help and give me some advice and tips on what to do to enhance these product pages
