The correct way to make it work is:

add_filter( 'woocommerce_email_headers', 'new_order_reply_to_admin_header', 20, 3 );

    if ( $email_id === 'new_order' ){
        $email = new WC_Email($email_id);
        $header = "Content-Type: " . $email->get_content_type() . "\r\n";
        $header .= 'Reply-to: ' . __('Administrator') . ' <' . get_option( 'admin_email' ) . ">\r\n";
    }
    return $header;
}
